During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS. In total about 100 000 charged-current neutrino interactions were located in the nuclear emulsion target and fully reconstructed. From this sample of events which was based on the data acquired by new automatic scanning systems, 1048 Do events were selected by a pattern recognition program. They were confirmed as neutral-particle decays through visual inspection. Fragmentation properties of deep-inelastic charm production were measured using these events. Distributions of the DO momentum, Feynman x (x(F)), z and tantheta(out), the transverse angle out of the leptonic plane defined by the muon and the neutrino, are presented. The mean value of z was measured to be (z) = 0.63 +/- 0.03(stat) +/- 0.01(syst). From fits to the z distribution, values for the Peterson parameter epsilon(P) = 0.108 +/- 0.017(stat) +/- 0.013(syst) and the Collins-Spiller parameter epsilon(CS) = 0.21(-0.04)(+0.05) (stat) +/- 0.04(syst) are found. For the average value of x(F) we find (x(F)) = 0.38 +/- 0.04(stat) +/- 0.03(syst) and 4 for the forward-backward asymmetry A = 0.79 +/- 0.14(stat) +/- 0.05(syst). The distribution of tantheta(out) was measured with an average value (tantheta(out)) = 0.030 +/- 0.002. (C) 2004 Elsevier B.V. All rights reserved.

Measurement of charm production in antineutrino charged-current interactions Onengut, G; et. al. (Elsevier BV, 2004-12-01) During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS collecting about 10(6) neutrino interactions. A measurement of (nu) over bar (mu)-induced charm production is performed by using the presence of a 5% (nu) over bar (mu) component in the nu(mu) beam. The measurement takes advantage of the capability to observe the decay topology in the emulsion. The analysis is based on a sample of charged-current interactions with at least one id...
Measurements of D-0 production and of decay branching fractions in neutrino-nucleon scattering Onengut, G; et. al. (Elsevier BV, 2005-05-05) During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy. In total about 100 000 charged-current neutrino interactions were located in the nuclear emulsion target and fully reconstructed. From this sample of events which was based on the data acquired by new automatic scanning systems, 1048 charged-current interactions with a Do in the final state were selected by a pattern recognition program and conf...
Determination of the semi-leptonic branching fraction of charm hadrons produced in neutrino charged-current interactions Kayis-Topaksu, A; et. al. (Elsevier BV, 2002-11-01) During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the CERN-SPS Wide Band Neutrino Beam. The improvements of the past few years in the automatic emulsion scanning systems allowed a sample of events located in emulsion to be used for studies of charm production. Based on a sample of 56 172nu(mu) charged-current interactions analysed so far, we find a value of B-mu = 0.093+/-0.009(stat.) +/-0.009(syst.) for the semi-leptonic branching fraction of charm hadrons. The result fo...
Measurement of the centrality dependence of J/psi yields and observation of Z production in lead-lead collisions with the ATLAS detector at the LHC Aad, G.; et. al. (Elsevier BV, 2011-03-14) Using the ATLAS detector, a centrality-dependent suppression has been observed in the yield of J/psi mesons produced in the collisions of lead ions at the Large Hadron Collider. In a sample of minimum-bias lead-lead collisions at a nucleon-nucleon centre of mass energy root s(NN) = 2.76 TeV, corresponding to an integrated luminosity of about 6.7 mu b(-1), J/psi mesons are reconstructed via their decays to mu(+)mu(-) pairs. The measured J/psi yield, normalized to the number of binary nucleon-nucleon collisio...
Measurement of the Z gamma production cross section in pp collisions at 8 TeV and search for anomalous triple gauge boson couplings Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2015-04-01) The cross section for the production of Z gamma in proton-proton collisions at 8 TeV is measured based on data collected by the CMS experiment at the LHC corresponding to an integrated luminosity of 19.5 fb(-1). Events with an oppositely-charged pair of muons or electrons together with an isolated photon are selected. The differential cross section as a function of the photon transverse momentum is measured inclusively and exclusively, where the exclusive selection applies a veto on central jets. The observ...
