The nuclear emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy from 1994 to 1997. In total, about 100 000 charged-current (CC) neutrino interactions with at least one identified muon were located in the emulsion target and fully reconstructed, using newly developed automated scanning systems. Charmed particles were searched for by a program recognizing particle decays. The observation of the decay in nuclear emulsion makes it possible to select a sample with very low background and minimal kinematical bias. In all, 2013 CC interactions with a charmed hadron candidate in the final state were selected and confirmed through visual inspection. The charm production rate induced by neutrinos relative to the CC cross-section is measured to be sigma(nu(mu)N -> mu(-)CX)/sigma(CC) = (5.75 +/- 0.32(stat) +/- 0.30(syst))%. The charm production cross-section as a function of neutrino energy is also obtained. The results are in good agreement with previous measurements. The charm-quark hadronization produces the following charmed hadrons with relative fractions (in %): f(D)(0) = 43.7 +/- 4.5, f(Lambda c)(+) = 19.2 +/- 4.2, f(D)(+) = 25.3 +/- 4.2 and f(Ds)(+) = 11.8 +/- 4.7.

Measurement of the Top Quark Pair Production Cross Section in Proton-Proton Collisions at root s=13 TeV Khachatryan, V.; et. al. (American Physical Society (APS), 2016-02-01) The top quark pair production cross section is measured for the first time in proton-proton collisions at root s = 13 TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of 43 pb(-1). The measurement is performed by analyzing events with at least one electron and one muon of opposite charge, and at least two jets. The measured cross section is 746 +/- 58(stat) +/- 53(syst) +/- 36(lumi) pb, in agreement with the expectation from the standard model.
Measurement of Dijet Angular Distributions and Search for Quark Compositeness in pp Collisions at root s=7 TeV Khachatryan, V.; et. al. (American Physical Society (APS), 2011-05-01) Dijet angular distributions are measured over a wide range of dijet invariant masses in pp collisions at root s = 7 TeV, at the CERN LHC. The event sample, recorded with the CMS detector, corresponds to an integrated luminosity of 36 pb(-1). The data are found to be in good agreement with the predictions of perturbative QCD, and yield no evidence of quark compositeness. With a modified frequentist approach, a lower limit on the contact interaction scale for left-handed quarks of Lambda(+) = 5.6 TeV (Lambda(...
Observation of Top Quark Production in Proton-Nucleus Collisions Sirunyan, A. M.; et. al. (American Physical Society (APS), 2017-12-01) The first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon center-of-mass energy of root(S)(NN) = 8.16 TeV. The measurement is performed using events with exactly one isolated electron or muon candidate and at least four jets. The data sample corresponds to an integrated luminosity of 174 nb(-1). The significance of the tt signal against the background-only hypothesis is above 5 standard d...
Towards Understanding the Origin of Cosmic-Ray Electrons Aguilar, M.; et. al. (American Physical Society (APS), 2019-03-13) Precision results on cosmic-ray electrons are presented in the energy range from 0.5 GeV to 1.4 TeV based on 28.1 x 10(6) electrons collected by the Alpha Magnetic Spectrometer on the International Space Station. In the entire energy range the electron and positron spectra have distinctly different magnitudes and energy dependences. The electron flux exhibits a significant excess starting from 42.1(-5.2)(+5.4) GeV compared to the lower energy trends, but the nature of this excess is different from the posit...
Measurement of the W+W- Cross Section in root s=7 TeV pp Collisions with ATLAS Aad, G.; et. al. (American Physical Society (APS), 2011-07-20) This Letter presents a measurement of the W+W- production cross section in root s = 7 TeV pp collisions by the ATLAS experiment, using 34 pb(-1) of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7 +/- 0.6 events. The measured cross section is 41(-16)(+20)(stat) +/- 5(syst) +/- 1(lumi) pb, which is consistent with the standard model prediction o...
