Abstract: For a large liquid-argon time-projection chamber (LArTPC) operating on or near the Earth's surface to detect neutrino interactions, the rejection of cosmogenic background is a critical and challenging task because of the large cosmic-ray flux and the long drift time of the time-projection chamber. We introduce a superior cosmic background rejection procedure based on the Wire-Cell three-dimensional (3D) event reconstruction for LArTPCs. From an initial 1:20 000 neutrino to cosmic-ray background ratio, we demonstrate these tools on data from the MicroBooNE experiment and create a high-performance generic neutrino event selection with a cosmic contamination of 14.9% (9.7%) for a visible energy region greater than O(200) MeV. The neutrino interaction selection efficiency is 80.4% and 87.6% for inclusive νμ charged-current and νe charged-current interactions, respectively. This significantly improved performance compared with existing reconstruction algorithms marks a major milestone toward reaching the scientific goals of LArTPC neutrino oscillation experiments operating near the Earth's surface.

We employ a fully-automated reconstruction chain capable of identifying EM showers of (100) MeV energy, relying on a combination of traditional reconstruction techniques together with novel machine-learning approaches. These studies demonstrate good energy resolution, and good agreement between data and simulation, relying on the reconstructed invariant π0 mass and other photon distributions for validation. The reconstruction techniques developed are applied to a selection of νμ + Ar → μ + π0 + X candidate events to demonstrate the potential for calorimetric separation of photons from electrons and reconstruction of π0 kinematics.

Abstract: This document was prepared by the MicroBooNE Collaboration using the resources of the Fermi National Accelerator Laboratory (Fermilab), a U.S. Department of Energy, Office of Science, HEP User Facility. Fermilab is managed by Fermi Research Alliance, LLC (FRA), acting under Contract No. DE-AC02-07CH11359. MicroBooNE is supported by the following: the U.S. Department of Energy, Office of Science, Offices of High Energy Physics and Nuclear Physics; the U.S. National Science Foundation; the Swiss National Science Foundation; the Science and Technology Facilities Council (STFC), part of the United Kingdom Research and Innovation; and The Royal Society (United Kingdom). Additional support for the laser calibration system and cosmic ray tagger was provided by the Albert Einstein Center for Fundamental Physics, Bern, Switzerland., We present upper limits on the production of heavy neutral leptons (HNLs) decaying to μπ pairs using data collected with the MicroBooNE liquid-argon time projection chamber (TPC) operating at Fermilab. This search is the first of its kind performed in a liquid-argon TPC. We use data collected in 2017 and 2018 corresponding to an exposure of 2.0×1020 protons on target from the Fermilab Booster Neutrino Beam, which produces mainly muon neutrinos with an average energy of ≈800 MeV. HNLs with higher mass are expected to have a longer time of flight to the liquid-argon TPC than Standard Model neutrinos. The data are therefore recorded with a dedicated trigger configured to detect HNL decays that occur after the neutrino spill reaches the detector. We set upper limits at the 90% confidence level on the element |Uμ4|2 of the extended PMNS mixing matrix in the range |Uμ4|2, Fermilab is managed by Fermi Research Alliance, LLC (FRA), acting under Contract No. DE-AC02-07CH11359

Abstract: We report the first measurement of the double-differential and total muon neutrino charged current inclusive cross sections on argon at a mean neutrino energy of 0.8 GeV. Data were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab Booster neutrino beam and correspond to 1.6×10^{20} protons on target of exposure. The measured differential cross sections are presented as a function of muon momentum, using multiple Coulomb scattering as a momentum measurement technique, and the muon angle with respect to the beam direction. We compare the measured cross sections to multiple neutrino event generators and find better agreement with those containing more complete treatment of quasielastic scattering processes at low Q^{2}. The total flux integrated cross section is measured to be 0.693±0.010(stat)±0.165(syst)×10^{-38} cm^{2}.

Abstract: Cosmic ray (CR) interactions can be a challenging source of background for neutrino oscillation and cross-section measurements in surface detectors. We present methods for CR rejection in measurements of charged-current quasielastic-like (CCQE-like) neutrino interactions, with a muon and a proton in the final state, measured using liquid argon time projection chambers (LArTPCs). Using a sample of cosmic data collected with the MicroBooNE detector, mixed with simulated neutrino scattering events, a set of event selection criteria is developed that produces an event sample with minimal contribution from CR background. Depending on the selection criteria used a purity between 50 and 80% can be achieved with a signal selection efficiency between 50 and 25%, with higher purity coming at the expense of lower efficiency. While using a specific dataset and selection criteria values optimized for the MicroBooNE detector, the concepts presented here are generic and can be adapted for various studies of exclusive $$\nu _{\mu }$$ ν μ CCQE interactions in LArTPCs.

This measurement is performed with the MicroBooNE detector, an 85 ton active mass liquid argon time projection chamber exposed to the Booster Neutrino Beam at Fermilab. This result on argon is compared to past measurements on lighter nuclei to investigate the scaling assumptions used in models of the production and transport of pions in neutrino-nucleus scattering. The techniques used are an important demonstration of the successful reconstruction and analysis of neutrino interactions producing electromagnetic final states using a liquid argon time projection chamber operating at the Earth's surface.

Abstract: We measure a large set of observables in inclusive charged current muon neutrino scattering on argon with the MicroBooNE liquid argon time projection chamber operating at Fermilab. We evaluate three neutrino interaction models based on the widely used GENIE event generator using these observables. The measurement uses a data set consisting of neutrino interactions with a final state muon candidate fully contained within the MicroBooNE detector. These data were collected in 2016 with the Fermilab Booster Neutrino Beam, which has an average neutrino energy of $$800~\hbox {MeV}$$ 800 MeV , using an exposure corresponding to $$ 5.0\times 10^{19}$$ 5.0 × 10 19 protons-on-target. The analysis employs fully automatic event selection and charged particle track reconstruction and uses a data-driven technique to separate neutrino interactions from cosmic ray background events. We find that GENIE models consistently describe the shapes of a large number of kinematic distributions for fixed observed multiplicity.

Abstract: The single-phase liquid argon time projection chamber (LArTPC) provides a large amount of detailed information in the form of fine-grained drifted ionization charge from particle traces. To fully utilize this information, the deposited charge must be accurately extracted from the raw digitized waveforms via a robust signal processing chain. Enabled by the ultra-low noise levels associated with cryogenic electronics in the MicroBooNE detector, the precise extraction of ionization charge from the induction wire planes in a single-phase LArTPC is qualitatively demonstrated on MicroBooNE data with event display images, and quantitatively demonstrated via waveform-level and track-level metrics. Improved performance of induction plane calorimetry is demonstrated through the agreement of extracted ionization charge measurements across different wire planes for various event topologies. In addition to the comprehensive waveform-level comparison of data and simulation, a calibration of the cryogenic electronics response is presented and solutions to various MicroBooNE-specific TPC issues are discussed. This work presents an important improvement in LArTPC signal processing, the foundation of reconstruction and therefore physics analyses in MicroBooNE., Comment: 54 pages, 36 figures; the first part of this work can be found at arXiv:1802.08709

Abstract: The development and operation of liquid-argon time-projection chambers for neutrino physics has created a need for new approaches to pattern recognition in order to fully exploit the imaging capabilities offered by this technology. Whereas the human brain can excel at identifying features in the recorded events, it is a significant challenge to develop an automated, algorithmic solution. The Pandora Software Development Kit provides functionality to aid the design and implementation of pattern-recognition algorithms. It promotes the use of a multi-algorithm approach to pattern recognition, in which individual algorithms each address a specific task in a particular topology. Many tens of algorithms then carefully build up a picture of the event and, together, provide a robust automated pattern-recognition solution. This paper describes details of the chain of over one hundred Pandora algorithms and tools used to reconstruct cosmic-ray muon and neutrino events in the MicroBooNE detector. Metrics that assess the current pattern-recognition performance are presented for simulated MicroBooNE events, using a selection of final-state event topologies.

Abstract: We report on the extraction of the structure functions F2 and DeltaxF(3) = xF(nu)(3)-xF(nu;)(3) from CCFR nu(mu)-Fe and nu;(mu)-Fe differential cross sections. The extraction is performed in a physics model-independent (PMI) way. This first measurement of DeltaxF(3), which is useful in testing models of heavy charm production, is higher than current theoretical predictions. The ratio of the F2 (PMI) values measured in nu(mu) and mu scattering is in agreement (within 5%) with the predictions of next-to-leading-order parton distribution functions using massive charm production schemes, thus resolving the long-standing discrepancy between the two sets of data.

Abstract: We report on a measurement of the neutrino-nucleon and antineutrino-nucleon differential cross sections in the CCFR detector. The measurement of the differential cross sections over a wide range of energies allows ΔχF 3 = χF 3 ν −χF 3 v and R to be extracted. ΔχF3 is related to the difference between the contributions of the strange and charm seas in the nucleon to production of massive charm quark. The results for ΔχF3 are compared to various massive charm NLO QCD models. The Q2 dependence of R for χ

Abstract: We present an improved determination of the proton structure functions $F_{2}$ and $xF_{3}$ from the CCFR $\nu $-Fe deep inelastic scattering (DIS) experiment. Comparisons to high-statistics charged-lepton scattering results for $F_{2}$ from the NMC, E665, SLAC, and BCDMS experiments, after correcting for quark-charge and heavy-target effects, indicate good agreement for $x>0.1$ but some discrepancy at lower x. The $Q^{2}$ evolution of the structure functions yields the quantum chromodynamics (QCD) scale parameter $\Lambda_{\bar{MS}}^{NLO,(4)}=337 \pm 28$(exp.) MeV. This corresponds to a value of the strong coupling constant at the scale of mass of the Z-boson of $\alpha _{S}(M_{Z}^{2})=0.119 \pm 0.002 (exp.) \pm 0.004 (theory)$ and is one of the most precise measurements of this quantity.

Abstract: Previous energy measurements of cosmic ray muons have used magnetic spectrometers to measure the momentum of muons. Measurements using magnets fail for muons in the TeV range because at ultra-high muon energies, the measurement error in the angular deflection of muons by the spectrometer becomes comparable to the total angula deflection. A new method for measuring the energies of TeV muons is investigated, using a sample of cosmic ray muons accumulated parasitically (or synergistically) by the CCFR neutrino detector. The method infers the muon energy from measurements of the energy deposited by the muon in many layers of an iron-scintillator calorimeter. Muons in the TeV energy range lose energy stochastically through e+et - pai production. The distribution of muon energy loss is used t estimate the most likely muon energy. The analysis suggest that this new method for measuring cosmic ray muon energ may be applicable in future detectors such as MINOS an AMANDA.

Abstract: Limits on ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\rightarrow}{\ensuremath{\nu}}_{e}({\overline{\ensuremath{\nu}}}_{e})$ oscillations based on a statistical separation of ${\ensuremath{\nu}}_{e}N$ charged current interactions in the CCFR detector at Fermilab are presented. Neutrino energies range from 30 to 600 GeV with a mean of 140 GeV, and ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ flight lengths vary from 0.9 to 1.4 km. The result excludes oscillations in the region with ${sin}^{2}2\ensuremath{\alpha}g1.8\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ for large $\ensuremath{\Delta}{m}^{2}(g1000{\mathrm{eV}}^{2})$ and $\ensuremath{\Delta}{m}^{2}g1.6{\mathrm{eV}}^{2}$ for ${sin}^{2}2\ensuremath{\alpha}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$. This result is the most stringent limit to date for $\ensuremath{\Delta}{m}^{2}g25{\mathrm{eV}}^{2}$ and it excludes the high $\ensuremath{\Delta}{m}^{2}$ oscillation region favored by the LSND experiment. The ${\ensuremath{\nu}}_{\ensuremath{\mu}}$-to- ${\ensuremath{\nu}}_{e}$ cross-section ratio was measured as a test of ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\leftrightarrow}{\ensuremath{\nu}}_{e}({\overline{\ensuremath{\nu}}}_{e})$ universality to be $1.026\ifmmode\pm\else\textpm\fi{}0.025(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.049(\mathrm{syst})$.

Abstract: We present limits on ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}})$ and ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\rightarrow}{\ensuremath{\nu}}_{e}({\overline{\ensuremath{\nu}}}_{e})$ oscillations based on a study of inclusive $\ensuremath{\nu}N$ interactions performed using the CCFR massive coarse-grained detector in the Fermilab Tevatron Quadrupole Triplet neutrino beam. The sensitivity to oscillations is from the difference in the longitudinal energy deposition pattern of ${\ensuremath{\nu}}_{\ensuremath{\mu}}N$ vs ${\ensuremath{\nu}}_{\ensuremath{\tau}}N$ or ${\ensuremath{\nu}}_{e}N$ charged-current interactions. The ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ energies ranged from 30 to 500 GeV with a mean of 140 GeV. The minimum and maximum ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ flight lengths are 0.9 and 1.4 km, respectively. For ${\ensuremath{\nu}}_{\ensuremath{\mu}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ oscillations, the lowest 90% confidence upper limit in ${sin}^{2}2\ensuremath{\alpha}$ of 2.7 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}3}$ is obtained at $\ensuremath{\Delta}{m}^{2}\ensuremath{\sim}50$ e${\mathrm{V}}^{2}$. This result is the most stringent limit to date for $25l\ensuremath{\Delta}{m}^{2}l90$ e${\mathrm{V}}^{2}$. For ${\ensuremath{\nu}}_{\ensuremath{\mu}}\ensuremath{\rightarrow}{\ensuremath{\nu}}_{e}$ oscillations, the lowest 90% confidence upper limit in ${sin}^{2}2\ensuremath{\alpha}$ of 1.9 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}3}$ is obtained at $\ensuremath{\Delta}{m}^{2}\ensuremath{\sim}350$ e${\mathrm{V}}^{2}$. This result is the most stringent limit to date for $250l\ensuremath{\Delta}{m}^{2}l450$ e${\mathrm{V}}^{2}$, and also excludes at 90% confidence much of the high $\ensuremath{\Delta}{m}^{2}$ region favored by the recent LSND observation.

Abstract: We have extracted the momentum dependence of the mean, the truncated mean and the most probable value of the energy deposited in a segmented, iron-scintillator, hadron calorimeter by high-energy muons. Data were drawn from a sample of momentum-analyzed, high-energy muons produced in charged-current neutrino interactions. The truncated mean energy deposition of high-energy muons traversing 20 calorimeter segments increases by approximately 16% per 100 GeV c increase in muon momentum over the range 25−125 GeV c ; the most probable energy deposition increases by approximately 7%. These results are important for experiments at high-energy colliders (e.g., Tevatron, SSC and LHC) which use the d E d x of high-energy muons to calibrate the response of electromagnetic and hadron calorimeters with tower geometry. The data are in qualitative agreement with GEANT3 (v3.15/308a) simulations.

The existing high-statistics xF3 determination by the CDHSW collaboration is compared to our data. The data presented here constitute the first corroboration of the QCD prediction of xF3 evolution at low-ϰ, and yields ΛMS=210±28±41 MeV, and a determination of the GLS sum rule at Q2 = 3 GeV2, SGLS = ∫ϰ1xFsϰ=2.50±0.018 (stat.)±0.078 (syst.). Our value of ΛMS yields α3(Mz) = .111 ± .002 ± .003 ± .003 (scale). Comparison of the neutrino determination of F2(ϰ, Q2) with that obtained from the charged-lepton (e or μ) scattering leads to a precise test of the mean-square charge prediction by the Quark Parton Model. The SLAC-CCFR and BCDMS structure function provide a consistent and precise set of structure functions over a large range of Q2.

Abstract: Neutrino and antineutrino interactions with two muons in the final state have been studied by the CCFR collaboration in the Fermilab Tevatron neutrino beam. The rate of neutrino- and antineutrino-induced prompt same-sign dimuon production in steel was measured using a sample of 220 μ−μ− events and 15 μ+μ+ events with Pμ > 9 GeV/c, and energies between 30 GeV and 600 GeV. After background subtraction, the prompt rate of same-sign dimuon production is (0.53 ± 0.24) × 10−4 per νμ charged-current event and (0.52 ± 0.33) × 10 −4 per ν μ charged-current event. After demanding Pμ1 ≥ 9 GeV/c, Pμ2 ≥ 5 GeV/c and 30 ≤ Eν ≤ 600 GeV a sample of 5044 ν μ 1062 ν μ induced μ ∓ μ ± events are observed. The data support the slow rescaling model of charm production with a value of mc = 1.31 ± .24 GeV/c2. The CKM matrix element Vcd=.209±0.012 and the nucleon strangeness content, ηe=.064−0.00065+0.00075 are measured with the strange sea x distribution found to be softer than its non-strange counterpart.

Abstract: The rate of neutrino- and antineutrino-induced prompt same-sign dimuon production in steel was measured using a sample of μ−μ− events and 25 μ+μ+ events withPμ>9 GeV/c, produced in 1.5 millionvμ and 0.3 million$\overline {v_\mu }$ induced charged-current events with energies between 30 GeV and 600 GeV. The data were obtained with the Chicago-Columbia-Fermilab-Rochester (CCFR) neutrino detector in the Fermilab Tevatron Quadrupole Triplet Neutrino Beam during experiments E 744 and E 770. After background subtraction, the prompt rate of same-sign dimuon production is (0.53±0.24)×10−4 pervμ charged-current event and (0.52±0.33)×10−4 per$\overline {v_\mu }$ charged-current event. The kinematic distributions of the same-sign dimuon events after background subtraction are consistent with those of the non-prompt background due to meson decays in the hadron shower of a charged-current event. Calculations ofc$\bar c$ gluon bremsstrahlung, based on improved measurements of the charm mass parameter and nucleon structure functions by the CCFR collaboration, yield a prompt rate of (0.09±0.39)×10−4 pervμ charged-current event. In this case,c$\bar c$ gluon bremsstrahlung is probably not an observable source of prompt same-sign dimuons.

Abstract: A high-statistics study by the Columbia-Chicago-Fermilab-Rochester Collaboration of opposite-sign dimuon events induced by neutrino-nucleon scattering at the Fermilab Tevatron is presented. A sample of 5044 ${\ensuremath{\nu}}_{\mathrm{\ensuremath{\mu}}}$ and 1062 \ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathrm{\ensuremath{\mu}}}$ induced ${\mathrm{\ensuremath{\mu}}}^{\ensuremath{\mp}}$${\mathrm{\ensuremath{\mu}}}^{\ifmmode\pm\else\textpm\fi{}}$ events with ${\mathit{P}}_{\mathrm{\ensuremath{\mu}}1}$\ensuremath{\ge}9 GeV/c, ${\mathit{P}}_{\mathrm{\ensuremath{\mu}}2}$\ensuremath{\ge}5 GeV/c, 30\ensuremath{\le}${\mathit{E}}_{\ensuremath{\nu}}$\ensuremath{\le}600 GeV, and 〈${\mathit{Q}}^{2}$〉=22.2 ${\mathrm{GeV}}^{2}$/${\mathit{c}}^{2}$ is observed. The data support the slow-rescaling model of charm production with a value of ${\mathit{m}}_{\mathit{c}}$=1.31\ifmmode\pm\else\textpm\fi{}0.24 ${\mathrm{GeV}}^{2}$/${\mathit{c}}^{2}$. The first measurement of the ${\mathit{Q}}^{2}$ dependence of the nucleon strange quark distribution xs(x) is presented. The data yield the Cabibbo-Kobayashi-Maskawa matrix element \ensuremath{\Vert}${\mathit{V}}_{\mathit{c}\mathit{d}}$\ensuremath{\Vert}=0.209\ifmmode\pm\else\textpm\fi{}0.012 and the nucleon fractional strangeness content ${\mathrm{\ensuremath{\eta}}}_{\mathit{s}}$=0.${064}_{\mathrm{\ensuremath{-}}0.007}^{+0.008}$.

Abstract: We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction of structure functions, and the derived Parton Distribution Functions (PDF's). This experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep Inelastic Scattering (DIS) events which is over two orders of magnitude larger than past samples. We outline an innovative method for fitting the structure functions using a parametrized energy shift which yields reduced systematic uncertainties. High statistics measurements, in combination with improved systematics, will enable NuSOnG to perform discerning tests of fundamental Standard Model parameters as we search for deviations which may hint of "Beyond the Standard Model" physics., National Science Foundation (U.S.), United States.

Abstract: The relative absence of \ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathrm{\ensuremath{\mu}}}$-induced charged current events with respect to ${\ensuremath{\nu}}_{\mathrm{\ensuremath{\mu}}}$-induced events at large (g0.45) and large y (g0.70) enables us to limit the right handed coupling of the weak current. Our data restrict \ensuremath{\Vert}\ensuremath{\eta}${\mathrm{\ensuremath{\Vert}}}^{2}$=\ensuremath{\Vert}${\mathit{g}}_{\mathit{R}}$/${\mathit{g}}_{\mathit{L}}$${\mathrm{\ensuremath{\Vert}}}^{2}$0.0 015 with 90% C.L. Within the framework of left-right symmetric models, this measurement imposes a limit upon the mixing angle of the left and right handed bosons. Unlike the limits imposed by the \ensuremath{\mu}-decay and nuclear \ensuremath{\beta}-decay experiments, our limit is valid irrespective of the mass of the right handed neutrino.

Abstract: This document describes the physics potential of a new fixed-target program based on a ~1 TeV proton source. Two proton sources are potentially available in the future: the existing Tevatron at Fermilab, which can provide 800 GeV protons for fixed-target physics, and a possible upgrade to the SPS at CERN, called SPS+, which would produce 1 TeV protons on target. In this paper we use an example Tevatron fixed-target program to illustrate the high discovery potential possible in the charm and neutrino sectors. We highlight examples which are either unique to the program or difficult to accomplish at other venues., United States.

Abstract: This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 2205 new measurements from 667 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. This edition features expanded coverage of CP violation in B mesons and of neutrino oscillations. For the first time we cover searches for evidence of extra dimensions (both in the particle listings and in a new review). Another new review is on Grand Unified Theories. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews (and errata) are also available on the Particle Data Group website: http://pdg.lbl.gov.

Abstract: We report on the extraction of $R\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}\frac{{\ensuremath{\sigma}}_{L}}{{\ensuremath{\sigma}}_{T}}$ from CCFR ${\ensuremath{\nu}}_{\ensuremath{\mu}}$-Fe and ${\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}$-Fe differential cross sections. The CCFR differential cross sections do not show the deviations from the QCD expectations that are seen in the CDHSW data at very low and very high $x$. $R$ as measured in ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ scattering is in agreement with $R$ as measured in muon and electron scattering. All data on $R$ for ${Q}^{2}g1{\mathrm{GeV}}^{2}$ are in agreement with a NNLO QCD calculation which uses NNLO parton distribution functions and includes target mass effects. We report on the first measurements of $R$ in the low $x$ and ${Q}^{2}l1{\mathrm{GeV}}^{2}$ region (where an anomalous large rise in $R$ for nuclear targets has been observed by the HERMES Collaboration).

Abstract: We report on the extraction of the structure functions F_2 and Delta xF_3 = xF_3nu-xF_3nub from CCFR neutrino-Fe and antineutrino-Fe differential cross sections. The extraction is performed in a physics model independent (PMI) way. This first measurement for Delta xF_3, which is useful in testing models of heavy charm production, is higher than current theoretical predictions. Within 5% the F_2 (PMI) values measured in neutrino and muon scattering are in agreement with the predictions of Next-to-Leading-Order PDFs (using massive charm production schemes), thus resolving the long-standing discrepancy between the two measurements., 3 pages, Presented by Arie Bodek at DPF2000 Conference, Columbus, Ohio, Aug. 2000

Abstract: Data from the CCFR E770 neutrino deep inelastic scattering experiment at Fermilab contain events with a large Bjorken x (x>0.7) and high momentum transfer [Q{sup 2}>50 (GeV/c){sup 2}]. A comparison of the data with a model based on no nuclear effects at large x shows a significant excess of events in the data. The addition of Fermi gas motion of the nucleons in the nucleus to the model does not explain the excess. Adding a higher momentum tail due to the formation of ''quasi-deuterons'' makes some improvement. An exponentially falling F{sub 2}{proportional_to}e{sup -s(x-x{sub 0})} at large x, predicted by ''multi-quark clusters'' and ''few-nucleon correlations,'' can describe the data. A value of s=8.3{+-}0.7(stat){+-}0.7(syst) yields the best agreement with the data. (c) 2000 The American Physical Society.

Abstract: Charm production by neutrino charged-current interactions produces two muon (dimuon) events which are easily identified. This signal provides an important method to measure the strange sea and the mass of the charm quark. Several experiments, including CCFR, CDHS and CHARM II, have performed analyses of such events. The results of these analyses are summarized with emphasis on CCFR and improvements made by NuTeV.

Abstract: We measure the energy loss of high-energy muons (up to 1 TeV) from cosmic-ray muons incident on the iron-scintillator calorimeter of the Chicago-Columbia-Fermilab-Rochester Collaboration (Lab E) neutrino detector at Fermilab. Measurements of the differential energy loss spectra in Fe and the average $\frac{\mathrm{dE}}{\mathrm{dx}}$ energy loss in Fe are presented as functions of muon energy and are compared against calculations. There is reasonable agreement between the measurements and calculations except in the region of small energy losses (under a few GeV) for 1-TeV muons, where the measurement is about 30% lower than the calculation. This level of agreement with theory implies that reliable simulations of the performance of muon detectors for future TeV colliders can be done.

Abstract: We searched for candidates of neutral heavy lepton (NHL) production in a sample of 2.6 million neutrino interactions in the Columbia‐Chicago‐Fermilab‐Rochester (CCFR) neutrino detector. No evidence for a NHL was found in the charged current density channel, NHL→μ−+X. A NHL with mass between 0.5 and 3.0 GeV/c2 has been excluded (at 90% CL) for couplings to muons between 1×10−2 and 1±10−4 of the Fermi strength, depending on the NHL mass. The results of a search for a neutral heavy particle decaying via the neutral channel are also discussed.

Abstract: Neutrino and antineutrino interactions with two muons in the final state have been studied by the CCFR collaboration in the Fermilab Tevatron neutrino beam. The rate of neutrino‐ and antineutrino‐induced prompt same‐sign dimuon production in steel was measured using a sample of 220 μ−μ− events and 15 μ+μ+ events with Pμ≳9 GeV/c, and energies between 30 GeV and 600 GeV. In addition, a sample of 5044 νμ and 1062 νμ induced opposite‐sign (μ∓μ±) events was also observed with Pμ1≥9 GeV/c, Pμ2≥5 GeV/c, and 30≤Eθ≤600 GeV. The opposite‐sign data support the slow rescaling model of charm production with a value of mc=1.31±0.24 GeV/c2. The CKM matrix element Vcd=0.209±0.012 and the nucleon strangeness content, ηs=0.064+0.0075−0.0065 are also extracted from the data. The first measurements of the Q2 dependence of the strange quark densities, xs(x), are also presented.
