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 for events with visible energy larger than 30 GeV, B-mu = 0.102+/-0.016(stat.) +/-0.010(syst.), can be combined with the existing measurements of the dimuon rate to yield a value of 0.219+/-0.022 for the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element \V-cd\.

Measurement of fragmentation properties of charmed particle production in charged-current neutrino 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. 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 p...
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...
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...
Measurement of the production cross section for pairs of isolated photons in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-01-01) The integrated and differential cross sections for the production of pairs of isolated photons is measured in proton-proton collisions at a centre-of-mass energy of 7TeV with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 36 pb(-1) is analysed. A next-to-leading-order perturbative QCD calculation is compared to the measurements. A discrepancy is observed for regions of the phase space where the two photons have an azimuthal angle difference Delta phi less than or sim...
