Abstract

The CALICE Semi-Digital Hadronic CALorimeter (SDHCAL) prototype using Glass Resistive Plate Chambers as a sensitive medium is the first technological prototype of a family of high-granularity calorimeters developed by the CALICE collaboration to equip the experiments of future leptonic colliders. It was exposed to beams of hadrons, electrons and muons several times in the CERN PS and SPS beamlines between 2012 and 2018. We present here a new method of particle identification within the SDHCAL using the Boosted Decision Trees (BDT) method applied to the data collected in 2015. The performance of the method is tested first with Geant4-based simulated events and then on the data collected by the SDHCAL in the energy range between 10 and 80 GeV with 10 GeV energy steps. The BDT method is then used to reject the electrons and muons that contaminate the SPS hadron beams. The rejection power of the new method is estimated to be as high as 99.0% for the muons and 99.4% for the electrons associated to a pion selection efficiency of about 95.0%.

Abstract

We review the development of silicon-based calorimeters from the very first applications of small calorimeters used in collider experiments to the large-scale systems that are being designed today. We discuss silicon-based electromagnetic calorimeters for future e− e+ colliders and for the upgrade of the CMS experiment's endcap calorimeter to be used in the high-luminosity phase of the LHC. We present the intrinsic advantages of silicon as an active detector material and highlight the enabling technologies that have made calorimeters with very high channel densities feasible. We end by discussing the outlook for further extensions to the silicon calorimeter concept, such as calorimeters with fine-pitched pixel detectors.

Abstract

Triple gauge-boson couplings gamma WW and ZWW involving single-photon, single-W and W-pair production are determined using data samples collected at LEP with the ALEPH detector at centre-of-mass energies between 183 and 209 GeV The integrated luminosity used is 700 pb(-1) for the single-photon measurement and 683 pb-1 for the W channels. Restricting the measurement to C- and P-conserving terms and applying local SU(2)(L) x U(1)(Y) gauge invariance, the measured values of the parameters g(1)(Z), kappa(gamma) and lambda(gamma) are: g(1)(Z) = 1.001 +/- 0.027(stat) +/- 0.013(syst), kappa(gamma) = 0.971 +/- 0.055(stat) +/- 0.030(syst), lambda(gamma) = -0.012 +/- 0.027(stat) +/- 0.011(syst) for single-parameter fits, where the two other parameters are fixed to their Standard Model values. Results are also presented for the cases where two or all three couplings are allowed to vary. An additional analysis using W-pair events is performed to measure the unconstrained real and imaginary parts of all 14 triple gauge-boson couplings and to perform an indirect search for a techni-p resonance. No deviations from the Standard Model expectations are observed and the lower limit on the techni-p mass is set to 600 GeV/c(2) at 95% confidence level. (c) 2005 Elsevier B.V. All rights reserved.

Abstract

An improved search for Bs oscillations is performed in the ALEPH data sample collected during the first phase of LEP, and reprocessed in 1998. Three analyses based on complementary event selections are presented. First, decays of Bs mesons into hadronic flavour eigenstates are fully reconstructed. This selection yields a small sample of candidates with excellent decay length and momentum resolution and high average Bs purity. Semileptonic decays with a reconstructed Ds- meson provide a second sample with larger statistics, high average Bs purity, but a poorer momentum and decay length resolution due to the partial decay reconstruction. Finally, semileptonic b-hadron decays are inclusively selected and yield the data sample with the highest sensitivity to Bs oscillations, as the much higher statistics compensate for the low average Bs purity and poorer time resolution. A lower limit is set at 10.9 ps-1 at 95% CL, significantly lower than the expected limit of 15.7 ps-1.

Abstract

The decay B0 -> J/psi K0_S is reconstructed with J/psi -> e+ e- or mu+ mu- and K0_S -> pi+ pi-. From the full ALEPH dataset at LEP1 of about 4 million hadronic Z decays, 23 candidates are selected with an estimated purity of 71%. They are used to measure the CP asymmetry of this decay, given by sin 2beta in the Standard Model, with the result sin 2beta = 0.84 +0.82-1.04 +-0.16. This is combined with existing measurements from other experiments, and increases the confidence level that CP violation has been observed in this channel to 98%. The decay B 0 → J /ψ K 0 S is reconstructed with J/ ψ →e + e − or μ + μ − and K 0 S → π + π − . From the full ALEPH dataset at LEP1 of about 4 million hadronic Z decays, 23 candidates are selected with an estimated purity of 71%. They are used to measure the CP asymmetry of this decay, given by sin2 β in the Standard Model, with the result sin 2β=0.84 +0.82 −1.04 ±0.16 . This is combined with existing measurements from other experiments, and increases the confidence level that CP violation has been observed in this channel to 98%.

Abstract

A search for B0s oscillations is performed using a sample of semileptonic b-hadron decays collected by the ALEPH experiment during 1991-1995. Compared to previous inclusive lepton analyses, the proper time resolution and b-flavour mistag rate are significantly improved. Additional sensitivity to B0s mixing is obtained by identifying subsamples of events having a B0s purity which is higher than the average for the whole data sample. Unbinned maximum likelihood amplitude fits are performed to derive a lower limit of Deltam_s>9.5ps^-1 at 95% CL. Combining with the ALEPH D-s based analyses yields Deltam_s>9.6ps^-1 at 95% CL., 23 pages, 10 figures

Abstract

All ALEPH measurements of branching ratios of tau decays involving kaons are summarized including a combination of results obtained with K^0_S and K^0_L detection. The decay dynamics are studied, leading to the determination of contributions from vector K^*(892) and K^{*}(1410), and axial-vector K_1(1270) and K_1(1400) resonances. Agreement with isospin symmetry is observed among the different final states. Under the hypothesis of the conserved vector current, the spectral function for the K\bar{K}\pi mode is compared with the corresponding cross section for low energy e^+e^- annihilation, yielding an axial-vector fraction of (94^{+6}_{-8})% for this mode. The branching ratio for tau decay into all strange final states is determined to be B(\tau^-\to X^-(S=-1)\nu_\tau)=(28.7\pm1.2)\times 10^{-3}. The measured mass spectra of the strange tau decay modes are exploited to derive the S=-1 spectral function. A combination of strange and nonstrange spectral functions is used to determine the strange quark mass and nonperturbative contributions to the strange hadronic width. A method is developed to avoid the bad convergence of the spin zero hadronic component, with the result m_s(M_\tau^2)=(176^{+46}_{-57}) MeV/c^2. The evolution down to 1 GeV gives m_s(1 {GeV}^2) = (234^{+61}_{-76}) MeV/c^2., Comment: 34 pages, 12 figures

Abstract

During 1997 the ALEPH experiment at LEP gathered $57 \pb$ of data at centre-of-mass energies near $183 ~\G$. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction $\ee\r\H\Z$. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: $\mH > 87.9 \Gcs$ at 95\% confidence level.

Abstract

Using a sample of four million hadronic Z events collected in ALEPH from 1991 to 1995, the decays D^{*+} --> D^0 pi_{s}^+, with D^0 decaying to K^- pi^+ or to K^+ pi^-, are studied. The relative br anching ratio $B(\D^0 \to \K^+ \pi^-) / B(\D^0 \to \K^- \pi^+)$ is measured to be ( 1.84 \pm 0.59(\stat) \pm 0.34(\syst). The two possible contributions to the $\decDW$ decay, doubly Cabibbo-suppr essed decays and D^0-$D^0bar mixing, are disentangled by measuring the proper-time distribution of the reconstructed D^0's. Assuming no interference between the two processes, the upper limit obtai ned on the mixing rate is 0.92% at 95 % CL. The possible effect of interference between the two amplitudes is also assessed.

Abstract

Searches for supersymmetric particles in channels with one or more photons and missing energy have been performed with data collected by the ALEPH detector at LEP. The data consist of 11.1 \pb\ at $\sqrt{s} = 161 ~\, \rm GeV$, 1.1 \pb\ at 170 \gev\ and 9.5 \pb\ at 172 GeV. The \eenunu\ cross se ction is measured. The data are in good agreement with predictions based on the Standard Model, and are used to set upper limits on the cross sections for anomalous photon production. These limits are compared to two different SUSY models and used to set limits on the neutralino mass. A limit of 71 \gevsq\ at 95\% C.L. is set on the mass of the lightest neutralin o ($\tau_{\chi_{1}^{0}} \leq $ 3 ns) for the gauge-mediated supersymmetry breaking and LNZ models.

Abstract

The data recorded by the ALEPH detector at centre-of-mass energies of 161, 170, and 172 GeV are analysed for signals of chargino and neutralino production. No evidence of a signal is found, although candidate events consistent with the expectations from Standard Model processes are observed. Limits at 95% C.L. on the production cross sections are derived and bounds on the parameters of the Minimal Supersymmetric Standard Model are set. The lower limit on the mass of the lightest chargino is 85.5 GeV/c^2 for gaugino-like charginos (mu = -500 GeV/c^2), and 85.0 GeV/c^2 for Higgsino-like charginos (M_2 = 500 GeV/c^2), for heavy sneutrinos (M(snu) > 200 GeV/c^2) and tanb = sqrt(2). The effect of light sleptons on chargino and neutralino limits is investigated. The assumptions of a universal slepton mass and a universal gaugino mass are relaxed, allowing less model-dependent limits to be obtained.

Abstract

A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LLE coupling has been performed using the data collected by ALEPH at centre-of-mass energies of 130-172 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation. This is translated into lower limits on the mass of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, charginos with masses less than 73 GeV and neutralinos with masses less than 23 GeV are excluded at 95% confidence level for any generation structure of the LLE coupling, and for neutralino, slepton or sneutrino LSPs.

Abstract

The data recorded by the ALEPH experiment at LEP at centre-of-mass energies of 161 GeV and 172 GeV were analysed to search for sleptons, the supersymmetric partners of leptons. No evidence for the production of these particles was found. The number of candidates observed is consistent with the background expected from four-fermion processes and gammagamma-interactions. Improved mass limits at 95% C.L. are reported., Comment: 17 pages, 3 figures, submitted to Phys. Lett. B

Abstract

An analysis of the properties of hadronic final states produced in electron-positron annihilation at centre-of-mass energies of 130 and 136 GeV is presented. The measurements are based on a data sample of 5.7 pb$^{-1}$ collected in November 1995 with the Aleph detector at LEP. Inclusive charged particle distributions, jet rates and event-shape distributions are measured and the results are compared with the predictions of QCD-based models. From the measured distributions quantities are determined for which the dependence on the centre-of-mass energy can be predicted by QCD, including the mean multiplicity of charged particles, the peak position of the inclusive distribution of $\xi = -\ln x_p$ ($x_p = p/p_{\rm beam}$), and the strong coupling constant $\alpha_s$. The QCD predictions are tested by comparing with corresponding measurements at $E_{\rm cm} = 91.2$ GeV and at lower energies.

Abstract

An improved measurement of the average b hadron lifetime is performed using a sample of 1.5 million hadronic Z decays, collected during the 1991-1993 runs of ALEPH, with the silicon vertex detector fully operational. This uses the three-dimensional impact parameter distribution of lepton tracks coming from semileptonic b decays and yields an average b hadron lifetime of 1.533 ± 0.013 ± 0.022 ps.

Abstract

From 64492 selected τ-pair events, produced at the Z0 resonance, the measurement of the tau decays into hadrons from a global analysis using 1991, 1992 and 1993 ALEPH data is presented. Special emphasis is given to the reconstruction of photons and π0,S, and the removal of fake photons. A detailed study of the systematics entering the π0 reconstruction is also given. A complete and consistent set of tau hadronic branching ratios is presented for 18 exclusive modes. Most measurements are more precise than the present world average. The new level of precision reached allows a stringent test of τ-μ universality in hadronic decays, gτ/gμ = 1.0013 ± 0.0095, and the first measurement of the vector and axial-vector contributions to the non-strange hadronic τ decay width: Rτ,V = 1.788 ± 0.025 and Rτ,A = 1.694 ± 0.027. The ratio (Rτ,V - Rτ,A)/(Rτ,V + Rτ,A), equal to (2.7 ± 1.3) %, is a measure of the importance of QCD non-perturbative contributions to the hadronic τ decay width. © Springer-Verlag 1996.

Abstract

The Lambda(b) polarization in hadronic Z decays is measured in semileptonic decays from the average energies of the charged lepton and the neutrino. In a data sample of approximately 3 million hadronic Z decays collected by the ALEPH detector at LEP between 1991 and 1994, 462 +/- 31 Lambda(b) candidates are selected using (Lambda pi(+))-lepton correlations. From this event sample, the Lambda(b) polarization is measured to be P-Lambda b = -0.23(-0.20)(+0.24)(stat.)(-0.07)(+0.08)(syst.).

Abstract

A search for pair production of new heavy leptons has been performed assuming different scenarios for the mixing of the new particles with Standard Model leptons. No candidate events were found in a data sample corresponding to an integrated luminosity of 5.6 pb(-1) collected by the ALEPH detector at centre-of-mass energies of 130 and 136 GeV. New limits on production cross-sections and on masses of sequential leptons were obtained which significantly extend the mass regions excluded at LEP1. For instance, charged heavy leptons with masses below 63.5 GeV/c(2) are excluded at 95% C.L. for mass differences to the associated neutral lepton of more than 7 GeV/c(2).

Abstract

The ratios of cross sections, Rb = a(e+e- → bb)/a(e+e- → hadrons) and R, = cr(e+e- → E)/a(e+e- → hadrons) and , and the forward-backward asymmetries and , have been measured by the four LEP experiments at centre-of-mass energies close to the Z boson mass, using a variety of heavy flavour identification techniques and analysis methods. The procedure adopted to combine these measurements is described here. It takes into account the statistical and systematic correlations among the measurements and their interdependences in a χ2 minimization. The procedure is illustrated using published measurements., Facultad de Ciencias Exactas

Abstract

The mean lifetime of the τ lepton is measured in a sample of 25700 τ pairs collected in 1992 with the ALEPH detector at LEP. A new analysis of the 1-1 topology events is introduced. In this analysis, the dependence of the impact parameter sum distribution on the daughter track momenta is taken into account, yielding improved precision compared to other impact parameter sum methods. Three other analyses of the one- and three-prong τ decays are updated with increased statistics. The measured lifetime is 293.5±3.1±1.7 fs. Including previous (1989-1991) ALEPH measurements, the combined τ lifetime is 293.7±2.7±1.6 fs. © Springer-Verlag 1996.

Abstract

The polarization of \Lambda baryons from Z decays is studied with the {\sc Aleph} apparatus. Evidence of longitudinal polarization of s quarks from Z decay is observed for the first time. The measured longitudinal \Lambda polarization is P^{\Lambda}_{L} = -0.32 \pm 0.07 for z = p/p_{\mathrm{beam}} > 0.3. This agrees with the prediction of -0.39 \pm 0.08 from the standard model and the constituent quark model, where the error is due to uncertainties in the mechanism for \Lambda production. The observed \Lambda polarization is diluted with respect to the primary s quark polarization by \Lambda baryons without a primary s quark. Measurements of the \Lambda forward-backward asymmetry and of the correlation between back-to-back \Lambda \bar{\Lambda} pairs are used to check this dilution. In addition the transverse \Lambda polarization is measured. An indication of transverse polarization, more than two standard deviations away from zero, is found along the normal to the plane defined by the thrust axis and the \Lambda direction. %

Abstract

A sample of 62249 τ-pair events is selected from data taken with the ALEPH detector in 1991, 1992 and 1993. The measurement of the branching fractions for τ decays into electrons and muons is presented with emphasis on the study of systematic effects from selection, particle identification and decay classification. The results obtained are: Be = 17.79±0.12(stat)±0.06(syst)(%) and Bμ = 17.31±0.11(stat)±0.05(syst)(%). Combined with the most recent. ALEPH determination of the τ lifetime, these results provide a relative measurement of the leptonic couplings in the weak charged current for transverse W bosons: gμ/ge = 1.0002±0.0051 and gτ/gμ = 0.9943±0.0065. © Springer-Verlag 1996.

Abstract

An upper limit for the tau-neutrino mass has been determined from the decay tau -> 5pi+- \nu_tau using data collected with the OPAL detector from 1991 to 1995 in e+e- collisions at \sqrt{s} ~ M_Z. A limit of 43.2 MeV at 95% CL is obtained using a two-dimensional method in the 5pi invariant mass and energy distribution from 22 selected events. Combining this result with OPAL's previously published measurement using tau+tau- -> 3h+- \bar{nu}_tau 3h-+ \nu_tau decays, a new combined limit of m_{nu_tau} < 27.6 MeV (95% CL) is obtained.
