Abstract: The results of an extensive campaign of measurements of the pi -> pi pi process in the nucleon and nuclei at intermediate energies are presented. The measurements were motivated by the study of strong pi pi correlations in nuclei. The analysis relies on the composite ratio C_{pi pi}^A, which accounts for the clear effect of the nuclear medium on the (pi pi) system. The comparison of the C_{pi pi}^A distributions for the (pi pi)_{I=J=0} and (pi pi)_{I=0,J=2} systems to the model predictions indicates that the C_{pi pi}^A behavior in proximity of the 2m_pi threshold is explainable through the partial restoration of chiral symmetry in nuclei., Comment: accepted for publication in Nucl.

Abstract: The T2K Collaboration reports evidence for electron neutrino appearance at the atmospheric mass splitting, vertical bar Delta m(32)(2)vertical bar approximate to 2.4 X 10(-3) eV(2). An excess of electron neutrino interactions over background is observed from a muon neutrino beam with a peak energy of 0.6 GeV at the Super-Kamiokande (SK) detector 295 km from the beam's origin. Signal and background predictions are constrained by data from near detectors located 280 m from the neutrino production target. We observe 11 electron neutrino candidate events at the SK detector when a background of 3.3 +/- 0.4(syst) events is expected. The background-only hypothesis is rejected with a p value of 0.0009 (3.1 sigma), and a fit assuming nu(mu) -> nu(e) oscillations with sin (2)2 theta(23) = 1, delta(CP) = 0 and vertical bar Delta m(32)(2)vertical bar = 2.4 X 10(-3) eV(2) yields sin (2)2 theta(13) = 0.088(-0.039)(+0.049)(stat + syst)., We thank the J-PARC accelerator team for the superb accelerator performance and CERN NA61 colleagues for providing essential particle production data and for their fruitful collaboration.

Abstract: T2K has performed the first measurement of nu(mu) inclusive charged current interactions on carbon at neutrino energies of similar to 1 GeV where the measurement is reported as a flux-averaged double differential cross section in muon momentum and angle. The flux is predicted by the beam Monte Carlo and external data, including the results from the NA61/SHINE experiment. The data used for this measurement were taken in 2010 and 2011, with a total of 10.8 x 10(19) protons-on-target. The analysis is performed on 4485 inclusive charged current interaction candidates selected in the most upstream fine-grained scintillator detector of the near detector. The flux-averaged total cross section is (phi) = (6.91 +/- 0.13(stat) +/- 0.84(syst)) x 10(-39) cm(2)/nucleon for a mean neutrino energy of 0.85 GeV., We thank the J-PARC accelerator team for the superb accelerator performance and CERN NA61 colleagues for providing essential particle production data and for their fruitful collaboration. We acknowledge the support of MEXT, Japan; NSERC, NRC and CFI, Canada; CEA and CNRS/IN2P3, France; DFG, Germany; INFN, Italy; Ministry of Science and Higher Education, Poland; RAS, RFBR and the Ministry of Education and Science of the Russian Federation; MEST and NRF, South Korea; MICINN and CPAN, Spain; SNSF and SER, Switzerland; STFC, UK; NSF and DOE, USA. We also thank CERN for their donation of the UA1/NOMAD magnet and DESY for the HERA-B magnet mover system. In addition, participation of individual researchers and institutions in T2K has been further supported by funds from: ERC (FP7), EU; JSPS, Japan; Royal Society, UK; DOE Early Career program, and the A. P. Sloan Foundation, USA.

Abstract: Precise measurement of neutrino beam direction and intensity was achieved based on a new concept with modularized neutrino detectors. INGRID (Interactive Neutrino GRID) is an on-axis near detector for the T2K long baseline neutrino oscillation experiment. INGRID consists of 16 identical modules arranged in horizontal and vertical arrays around the beam center. The module has a sandwich structure of iron target plates and scintillator trackers. INGRID directly monitors the muon neutrino beam profile center and intensity using the number of observed neutrino events in each module. The neutrino beam direction is measured with accuracy better than 0.4 mrad from the measured profile center. The normalized event rate is measured with 4% precision., Comment: 32 pages, 27 figures, submitted to Nucl. Instr. and Meth. A

Abstract: Lepton family number violation is tested by searching for $\mu^+\to e^+X^0$ decays among the 5.8$\times 10^8$ positive muon decay events analyzed by the TWIST collaboration. Limits are set on the production of both massless and massive $X^0$ bosons. The large angular acceptance of this experiment allows limits to be placed on anisotropic $\mu^+\to e^+X^0$ decays, which can arise from interactions violating both lepton flavor and parity conservation. Branching ratio limits of order $10^{-5}$ are obtained for bosons with masses of 13 - 80 MeV/c$^2$ and with different decay asymmetries. For bosons with masses less than 13 MeV/c$^{2}$ the asymmetry dependence is much stronger and the 90% limit on the branching ratio varies up to $5.8 \times 10^{-5}$. This is the first study that explicitly evaluates the limits for anisotropic two body muon decays., Comment: 7 pages, 5 figures, 2 tables, accepted by PRD

Abstract: Differential cross sections for pi- p and pi+ p elastic scattering were measured at five energies between 19.9 and 43.3 MeV. The use of the CHAOS magnetic spectrometer at TRIUMF, supplemented by a range telescope for muon background suppression, provided simultaneous coverage of a large part of the full angular range, thus allowing very precise relative cross section measurements. The absolute normalisation was determined with a typical accuracy of 5 %. This was verified in a simultaneous measurement of muon proton elastic scattering. The measured cross sections show some deviations from phase shift analysis predictions, in particular at large angles and low energies. From the new data we determine the real part of the isospin forward scattering amplitude., 13 pages, 5 figures. To appear in PLB

Abstract: An analysis of new data for the reaction π±p→π±π+n at incident energies between 223 and 284 MeV is presented. π+π− cross sections are obtained via Goebel-Chew-Low techniques by extrapolation to the pion pole using the pseudoperipheral approximation. A consistency check between the present experimental results and previous experiments at higher energies is made using Roy equations. The isospin 0, S-wave ππ scattering length was obtained using a variety of methods. The result obtained from a threshold expansion is a00=0.204±0.014 (statistical) ±0.008 (systematic) in inverse pion mass units. It is shown that there are significant differences between the reaction mechanisms for the (π−π+) and (π+π+) channels.

Abstract: Analyzing powers for $\ensuremath{\pi}p$ elastic scattering were measured using the CHAOS spectrometer at energies spanning the \ensuremath{\Delta}(1232) resonance. This work presents ${\ensuremath{\pi}}^{+}$ data at the pion kinetic energies 117, 130, 139, 155, 169, 180, 193, 218, 241, and 267 MeV and ${\ensuremath{\pi}}^{\ensuremath{-}}$ data at 87, 117, 193, and 241 MeV, covering an angular range of $50\ifmmode^\circ\else\textdegree\fi{}l~{\ensuremath{\theta}}_{\mathrm{c}.\mathrm{m}.}l~180\ifmmode^\circ\else\textdegree\fi{}$ at the higher energies and $90\ifmmode^\circ\else\textdegree\fi{}l~{\ensuremath{\theta}}_{\mathrm{c}.\mathrm{m}.}l~180\ifmmode^\circ\else\textdegree\fi{}$ at the lower energies. Unique features of the spectrometer acceptance were employed to reduce systematic errors. Single-energy phase shift analyses indicate the resulting ${S}_{11}$ and ${S}_{31}$ phases favor the results of the SM95 phase shift analysis over that of the older KH80 analysis.

Abstract: The total cross section of the ${}^{4}\mathrm{He}({\ensuremath{\pi}}^{+},{\ensuremath{\pi}}^{\ensuremath{-}})$ reaction was measured for ${\ensuremath{\pi}}^{+}$ kinetic energies ranging from 70 to 130 MeV using the CHAOS spectrometer at TRIUMF and a liquid ${}^{4}\mathrm{He}$ target. Around ${T}_{\ensuremath{\pi}}=90\mathrm{MeV},$ total cross sections exceed conventional model predictions by a factor of 3, whereas at ${T}_{\ensuremath{\pi}}=70\mathrm{MeV}$ and for ${T}_{\ensuremath{\pi}}g130\mathrm{MeV}$ the data are consistent with these calculations. An attempt is made to understand this behavior by assuming the production of the hypothetical ${d}^{\ensuremath{'}}$ dibaryon.

Abstract: New experimental results on the π+d → π+π−pp and π+d → π+π+nn reactions at Tπ1 = 283 MeV are presented. In-plane coincidence data were taken with the CHAOS spectrometer using pions from the M11 channel at TRIUMF. Because of the quasi-free nature of the pion-production reaction, the present study is equivalent to studying the elementary π+N → π+π±N reactions on protons and neutrons simultaneously. These exclusive measurements provide a set of many-fold differential cross sections which are an ideal testing ground for microscopic models describing the πN → ππN reaction. The interpretation of the data relies on a model which is based on effective chiral Lagrangians to describe the piece of the reaction that includes only π's and N's, and on effective Lagrangians to account for intermediate Δ's and N ∗ ' s . The measured many-fold differential cross sections are used to constrain some parameters of the model (ξ, fΔ, C, g N ∗ Δπ and g N ∗ Nπ ). Finally, the π+π± invariant mass distributions display no evidence of strongly interacting pion pairs in either the I = J = 0 or the I = 2J = 0 channels.

Abstract: Using the CHAOS spectrometer at TRIUMF the total cross sections and outgoing pion momentum distributions for the 4 He( π + , π − ) reaction were measured for π + kinetic energies from 70 to 130 MeV. At energies around 100 MeV the total cross sections show an excess by a factor 3 over conventional model calculations which could be ascribed to a contribution from a hypothetical d ′ dibaryon.

Abstract: The pion production reaction $\pi^+ \to \pi^+\pi^{\pm}$ on $^{45}Sc$ was studied at incident pion energies of $T_{\pi^{+}}$ = 240, 260, 280, 300, and 320 MeV. The experiment was performed using the $M11$ pion-channel at TRIUMF, and multiparticle events, ($\pi^+,\pi^+\pi^{\pm}$) and ($\pi^+,\pi^+\pi^{\pm}p$), were detected with the CHAOS spectrometer. Results are reported in the form of both differential and total cross sections, and are compared to theoretical predictions and the reaction phase space. The present investigation of the T-dependence of the $\pi^+ A \to \pi^+\pi^{\pm} A'$ reaction complements earlier examinations of the A-dependence of the reaction, which was measured using $^{2}H$, $^{4}He$, $^{12}C$, $^{16}O$, $^{40}Ca$, and $^{208}Pb$ targets at $\sim$280 MeV. Some general properties of the pion-induced pion production reaction in nuclear matter will be presented, based on the combined results of the two studies., Comment: 23 pages, Latex, accepted for publication in Nucl.

Abstract: The T2K experiment has observed electron neutrino appearance in a muon neutrino beam produced 295 km from the Super-Kamiokande detector with a peak energy of 0.6 GeV. A total of 28 electron neutrino events were detected with an energy distribution consistent with an appearance signal, corresponding to a significance of 7.3$\sigma$ when compared to 4.92 $\pm$ 0.55 expected background events. In the PMNS mixing model, the electron neutrino appearance signal depends on several parameters including three mixing angles $\theta_{12}$, $\theta_{23}$, $\theta_{13}$, a mass difference $\Delta m^2_{32}$ and a CP violating phase $\delta_{\mathrm{CP}}$. In this neutrino oscillation scenario, assuming $|\Delta m^2_{32}| = 2.4 \times 10^{-3}$ $\rm eV^2$, $\sin^2 \theta_{23} = 0.5$, and $\Delta m^2_{32} >0$ ($\Delta m^2_{32}, Comment: 8 pages, 6 figures

Abstract: We report the first measurement of the neutrino-oxygen neutral-current quasielastic (NCQE) cross section. It is obtained by observing nuclear deexcitation $\gamma$-rays which follow neutrino-oxygen interactions at the Super-Kamiokande water Cherenkov detector. We use T2K data corresponding to $3.01 \times 10^{20}$ protons on target. By selecting only events during the T2K beam window and with well-reconstructed vertices in the fiducial volume, the large background rate from natural radioactivity is dramatically reduced. We observe 43 events in the $4-30$ MeV reconstructed energy window, compared with an expectation of 51.0, which includes an estimated 16.2 background events. The background is primarily nonquasielastic neutral-current interactions and has only 1.2 events from natural radioactivity. The flux-averaged NCQE cross section we measure is $1.55 \times 10^{-38}$ cm$^2$ with a 68\% confidence interval of $(1.22, 2.20) \times 10^{-38}$ cm$^2$ at a median neutrino energy of 630 MeV, compared with the theoretical prediction of $2.01 \times 10^{-38}$ cm$^2$., Comment: 10 pages, 6 figures

Abstract: New data from the T2K neutrino oscillation experiment produce the most precise measurement of the neutrino mixing parameter theta_{23}. Using an off-axis neutrino beam with a peak energy of 0.6 GeV and a data set corresponding to 6.57 x 10^{20} protons on target, T2K has fit the energy-dependent nu_mu oscillation probability to determine oscillation parameters. Marginalizing over the values of other oscillation parameters yields sin^2 (theta_{23}) = 0.514 +0.055/-0.056 (0.511 +- 0.055), assuming normal (inverted) mass hierarchy. The best-fit mass-squared splitting for normal hierarchy is Delta m^2_{32} = (2.51 +- 0.10) x 10^{-3} eV^2/c^4 (inverted hierarchy: Delta m^2_{13} = (2.48 +- 0.10) x 10^{-3} eV^2/c^4). Adding a model of multinucleon interactions that affect neutrino energy reconstruction is found to produce only small biases in neutrino oscillation parameter extraction at current levels of statistical uncertainty., Comment: 8 pages, 4 figures.

18. Spin-transfer measurements of theπd→→p→preaction at energies spanning theΔresonance

Abstract: The first spin-transfer experiment performed for the $\ensuremath{\pi}d\ensuremath{\rightarrow}\ensuremath{\rightarrow}p\ensuremath{\rightarrow}p$ reaction is described. Three spin-transfer parameters for this $\ensuremath{\pi}$-absorption process were determined, ${K}_{\mathrm{LS}}^{a}$, ${K}_{\mathrm{SS}}^{a}$, and ${K}_{\mathrm{NN}}^{a}$, which correspond to the \ensuremath{\pi}-production parameters, ${K}_{\mathrm{SL}}^{p}$, ${K}_{\mathrm{SS}}^{p}$, and ${K}_{\mathrm{NN}}^{p}$, of the time-reversed $p\ensuremath{\rightarrow}p\ensuremath{\rightarrow}d\ensuremath{\rightarrow}\ensuremath{\pi}$ process. Each observable was measured at a single angle for a number of energies spanning the $\ensuremath{\Delta}$ resonance of this system. The results are compared with the predictions of published partial wave amplitude fits which are primarily based on existing data for the time-reversed $\mathrm{pp}\ensuremath{\rightarrow}d\ensuremath{\pi}$ reaction, and also with the predictions of two current theories. The failure of these theories to describe the fundamental features of the data clearly demonstrates the need for further theoretical work in this area.

19. ADependence of the(π+,π+π±)Reaction near the2mπThreshold

Abstract: The ${}^{2}\mathrm{H}{,}^{12}\mathrm{C}{,}^{40}\mathrm{Ca}{,}^{208}\mathrm{Pb}({\ensuremath{\pi}}^{+},{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}})$ reactions have been studied at ${T}_{{\ensuremath{\pi}}^{+}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}282.7\phantom{\rule{0ex}{0ex}}\mathrm{MeV}$, and the ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ invariant mass distributions ${M}_{{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}}^{A}$ measured down to the ${2m}_{\ensuremath{\pi}}$ threshold. The ${M}_{{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}}^{A}$ yield near threshold is close to zero for $A\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2,$ and increases dramatically with increasing A (from 12 to 40 to 208). A phase analysis indicates that the ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ pairs in this range of ${M}_{{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}}^{A}$ have $J\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}I\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$. In the case of ${M}_{{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}}^{A},$ there is some strength near threshold regardless of A, and the ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$ pairs have $J\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0,I\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2$. The experimental results indicate that nuclear matter strongly modifies the \ensuremath{\pi}\ensuremath{\pi} interaction in the $J\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}I\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$ channel.

20. Role of quasideuteron absorption in theLi6(π+,pp) reaction atTπ+=100, 165 MeV

Subjects: Physics, Nuclear and High Energy Physics, Pion, Helium-4, Deuterium, Pi, Absorption (logic), Atomic physics, Nuclear environment
Abstract: Differential and total cross sections for ${\mathrm{\ensuremath{\pi}}}^{+}$ absorption on $^{6}\mathrm{Li}$, leading to the pp${+}^{4}$${\mathrm{He}}_{\mathrm{g}.\mathrm{s}.}$, pp${+}^{4}$${\mathrm{He}}^{\mathrm{*}}$, and pp+X final states, are presented at incident pion energies of 100 and 165 MeV. We conclude that most of the cross section is confined to the level of coplanarity expected from quasideuteron absorption in the nuclear environment and that the contributions of nonquasideuteron absorption mechanisms are small. \textcopyright{} 1996 The American Physical Society.

Abstract: The Tokai-to-Kamioka (T2K) experiment studies neutrino oscillations using an off-axismuon neutrino beam with a peak energy of about 0.6 GeV that originates at the Japan Proton Accelerator Research Complex accelerator facility. Interactions of the neutrinos are observed at near detectors placed at 280 m from the production target and at the far detector-Super-Kamiokande-located 295 km away. The flux prediction is an essential part of the successful prediction of neutrino interaction rates at the T2K detectors and is an important input to T2K neutrino oscillation and cross section measurements. A FLUKA and GEANT3-based simulation models the physical processes involved in the neutrino production, from the interaction of primary beam protons in the T2K target, to the decay of hadrons and muons that produce neutrinos. The simulation uses proton beam monitor measurements as inputs. The modeling of hadronic interactions is reweighted using thin target hadron production data, including recent charged pion and kaon measurements from the NA61/SHINE experiment. For the first T2K analyses the uncertainties on the flux prediction are evaluated to be below 15% near the flux peak. The uncertainty on the ratio of the flux predictions at the far and near detectors is less than 2% near the flux peak., We thank the J-PARC accelerator team for the superb accelerator performance and the J-PARC center for the continuous support of the T2K experiment. We are grateful to the NA61/SHINE collaboration and FLUKA team for their assistance to make our data-driven flux prediction.

Abstract: As part of an experimental study of the {pi}{ital NN} system, the pion-deuteron breakup reaction {pi}{sup +}{ital {rvec d}}{r_arrow}{ital pn}{pi}{sup +} was investigated at intermediate energies. Distributions of the vector analyzing power {ital iT}{sub 11} versus outgoing proton momentum {ital P}{sub {ital p}} are presented for 36 {pi}{ital p} angle pairs in the range of scattering angles 20{degree}{le}{theta}{sub {ital p}}{le}51{degree}, 62{degree}{le}{theta}{sub {pi}}{le}124{degree} at 228 and 134 MeV. These include 7 previously unmeasured angle pairs at 228 MeV and 20 new pairs at 134 MeV. In all regions of overlap with previous measurements, there is excellent agreement. There is generally excellent agreement with relativistic Faddeev predictions, except in the {ital np} final-state interaction region at 228 MeV. This is in contrast to the cross-section measurements, which are not well described by the theory.

Abstract: The Tokai to Kamioka (T2K) experiment studies neutrino oscillations using a beam of muon neutrinos produced by an accelerator. The neutrinos travel from J-PARC on the east coast of Japan and are detected 295 kilometers further away in the Super-Kamiokande detector. A complex of near detectors located 280 meters away from the neutrino production target is used to better characterize the neutrino beam and reduce systematic uncertainties. The experiment aims at measuring electronic neutrino appearance ( ν μ → ν e oscillation) to measure the neutrino mixing angle θ 13 , and muon neutrino disappearance to measure the neutrino mixing angle θ 23 and mass splitting | Δ m 32 2 |. We report here electron neutrino appearance results using three years of data, recorded until the 2012 summer, as well as muon neutrino disappearance results based on the data coming from the first two years of the experiment.

Abstract: T2K is a long-baseline neutrino oscillation experiment searching for $\nu_e$ appearance in a $\nu_{\mu}$ beam. The beam is produced at the J-PARC accelerator complex in Tokai, Japan, and the neutrinos are detected by the Super-Kamiokande detector located 295 km away in Kamioka. A suite of near detectors (ND280) located 280 m downstream of the production target is used to characterize the components of the beam before they have had a chance to oscillate and to better understand various neutrino interactions on several nuclei. This paper describes the design and construction of two massive fine-grained detectors (FGDs) that serve as active targets in the ND280 tracker. One FGD is composed solely of scintillator bars while the other is partly scintillator and partly water. Each element of the FGDs is described, including the wavelength shifting fiber and Multi-Pixel Photon Counter used to collect the light signals, the readout electronics, and the calibration system. Initial tests and {\normalsize\em in situ} results of the FGDs' performance are also presented.

Abstract: We report a measurement of muon-neutrino disappearance in the T2K experiment. The 295-km muon-neutrino beam from Tokai to Kamioka is the first implementation of the off-axis technique in a long-baseline neutrino oscillation experiment. With data corresponding to 1.43 × 10(20) protons on target, we observe 31 fully-contained single μ-like ring events in Super-Kamiokande, compared with an expectation of 104 ± 14(syst) events without neutrino oscillations. The best-fit point for two-flavor νμ → ντ oscillations is sin 2(2θ(23)) = 0.98 and |Δm(2)(32)| = 2.65 × 10(−3) eV2. The boundary of the 90% confidence region includes the points (sin2 (2θ(23)), |Δm(2)(32)|) = (1.0, 3.1 × 10(−3) eV2), (0.84, 2.65 × 10(−3) eV2) and (1.0, 2.2 × 10(−3) eV2)., Physical Review D, 85 (3), ISSN:1550-7998, ISSN:0556-2821, ISSN:1550-2368

Abstract: As part of an experimental study of the [pi][ital NN] system, the pion absorption reaction, [pi][sup +][ital [rvec d]][r arrow][ital pp], is investigated at low energy. Angular distributions of the vector analyzing power, [ital iT][sub 11], are presented for six complementary angle pair coincidences at 65 MeV and five pairs at 25 MeV. There is good agreement with previous measurements, and a significant improvement in uncertainties has been achieved. Results are compared with theoretical predictions based on three different approaches. The best agreement is with a relativistic Faddeev calculation by the Lyon group. Calculations based on the partial wave solutions of Arndt [ital et] [ital al]. are compared with the data at both energies.

Abstract: The T2K experiment observes indications of $\nu_\mu\rightarrow \nu_e$ appearance in data accumulated with $1.43\times10^{20}$ protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with $|\Delta m_{23}^2|=2.4\times10^{-3}$ eV$^2$, $\sin^2 2\theta_{23}=1$ and $\sin^2 2\theta_{13}=0$, the expected number of such events is 1.5$\pm$0.3(syst.). Under this hypothesis, the probability to observe six or more candidate events is 7$\times10^{-3}$, equivalent to 2.5$\sigma$ significance. At 90% C.L., the data are consistent with 0.03(0.04)$, Comment: 20 pages, 6 figures, version published in PRL

Abstract: The time dependence of muon spin relaxation has been measured in high purity aluminum and silver samples in a longitudinal 2 T magnetic field at room temperature, using time-differential \musr. For times greater than 10 ns, the shape fits well to a single exponential with relaxation rates of $\lambda_{\textrm{Al}} = 1.3 \pm 0.2\,(\textrm{stat.}) \pm 0.3\,(\textrm{syst.})\,\pms$ and $\lambda_{\textrm{Ag}} = 1.0 \pm 0.2\,(\textrm{stat.}) \pm 0.2\,(\textrm{syst.})\,\pms$.

Abstract: The T2K experiment is a long-baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle {\theta}_{13} by observing {\nu}_e appearance in a {\nu}_{\mu} beam. It also aims to make a precision measurement of the known oscillation parameters, {\Delta}m^{2}_{23} and sin^{2} 2{\theta}_{23}, via {\nu}_{\mu} disappearance studies. Other goals of the experiment include various neutrino cross section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem., Comment: 33 pages, 32 figures, Submitted and accepted by NIM A.

Abstract: Measurements of the analyzing power for the {sup 13}{rvec C}({pi}{sup {plus minus}},{pi}{sup {plus minus}}) reaction at {ital T}{sub {pi}}=100 MeV have been made at TRIUMF using a polarized target consisting of 99% {sup 13}C enriched butanol. Data were obtained for the ground and 3.68 MeV excited states at angles from 110{degree} to 150{degree} in 10{degree} steps. The data are consistent with zero asymmetry throughout most of this angular range. Uncertainties are typically {plus minus}15%, which is sufficient to discriminate among some, but not all, of the currently available theoretical predictions.

Abstract: We present the first measurement of the energy spectrum up to 70 MeV of electrons from the decay of negative muons after they become bound in $^{27}\mathrm{Al}$ atoms. The data were taken with the TWIST apparatus at TRIUMF. We find a muon lifetime of $(864.6\ifmmode\pm\else\textpm\fi{}1.2)\text{ }\text{ }\mathrm{ns}$, in agreement with earlier measurements. The asymmetry of the decay spectrum is consistent with zero, indicating that the atomic capture has completely depolarized the muons. The measured momentum spectrum is in reasonable agreement with theoretical predictions at the higher energies, but differences around the peak of the spectrum indicate the need for $\mathcal{O}(\ensuremath{\alpha})$ radiative corrections to the calculations. The present measurement is the most precise measurement of the decay spectrum of muons bound to any nucleus.

Abstract: The first spin-transfer observables for the {pi}{bold d}{r arrow}{bold p}{ital p} reaction have been measured at a number of energies spanning the {Delta} resonance in this system. These parameters correspond to {ital K}{sub {ital S}{ital L}} and {ital K}{sub {ital S}{ital S}} of the {ital p}{bold p}{r arrow}{bold d}{pi} reaction for incident proton energies ranging from 600 to 800 MeV. Such data can provide an important constraint on the determination of the partial-wave amplitudes describing this fundamental reaction. The discrepancies between our data, theoretical predictions, and values calculated from published partial-wave amplitudes demonstrate the need for further work in this area.

Abstract: An analysis of new data for the reaction p6p!p6p1n at incident energies between 223 and 284 MeV is presented. p1p2 cross sections are obtained via Goebel-Chew-Low techniques by extrapolation to the pion pole using the pseudoperipheral approximation. A consistency check between the present experimental results and previous experiments at higher energies is made using Roy equations. The isospin 0, S-wave pp scattering length was obtained using a variety of methods. The result obtained from a threshold expansion is a0 0 50.20460.014 ~statistical! 60.008 ~systematic! in inverse pion mass units. It is shown that there are significant differences between the reaction mechanisms for the (p2p1) and (p1p1) channels.

Abstract: The pion induced pion production reactions π±p⃗π+π±n were studied at projectile incident energies of 223, 243, 264, 284, and 305 MeV, using a cryogenic liquid hydrogen target. The Canadian High Acceptance Orbit Spectrometer was used to detect the two outgoing pions in coincidence. The experimental results are presented in the form of single differential cross sections. Total cross sections obtained by integrating the differential quantities are also reported. In addition, the invariant mass distributions from the (π+π-) channel were fitted to determine the parameters for an extended model based on that of Oset and Vicente-Vacas. We find the model parameters obtained from fitting the (π+π-) data do not describe the invariant mass distributions in the (π+π+) channel.

Abstract: The TWIST Collaboration has performed new measurements of two of the parameters that describe muon decay: {rho}, which governs the shape of the overall momentum spectrum, and {delta}, which governs the momentum dependence of the parity-violating decay asymmetry. This analysis gives the results {rho}=0.750 14{+-}0.000 17(stat){+-}0.000 44(syst){+-}0.000 11({eta}), where the last uncertainty arises from the correlation between {rho} and the decay parameter {eta}, and {delta}=0.750 67{+-}0.000 30(stat){+-}0.000 67(syst). These are consistent with the value of 3/4 given for both parameters in the standard model of particle physics, and are a factor of two more precise than the measurements previously published by TWIST. A new global analysis of all available muon decay data incorporating these results is presented. Improved lower and upper limits on the decay parameter P{sub {mu}}{sup {pi}}{xi} of 0.995 24

Abstract: A broad goal of many few body physics experiments at intermediate energies is to identify shortcomings of our "conventional" descriptions based on nucleons, nucleon resonances and mesons. Fkom these shortcomings it is often hoped to glean some evidence for the contributions of quarks and gluons. In addition one establishes specific oals for particular reaction channels, which upon realization furthers the empiric3 understanding of that channel, and in some small way also contributes to the above broad goal. Studies of the set of reactions involving the n-NN system must take into account the fact that this system is composed of a coupled set of reactions and that what is learned from one channel improves our understanding of the other coupled channels.

The results are consistent with two earlier measurements by this group employing different experimental techniques at 67 MeV and higher incident pion energies. The ${\mathrm{\ensuremath{\pi}}}^{\mathrm{\ensuremath{-}}}$p cross sections are in good agreement with currently accepted phase-shift analyses, but the corresponding ${\mathrm{\ensuremath{\pi}}}^{+}$p predictions are typically 15% higher at large angles than the ${\mathrm{\ensuremath{\pi}}}^{+}$p cross sections reported here.
