The emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS between the years 1994 and 1997. In total about 130.000 neutrino interactions were located in the nuclear emulsion target and fully reconstructed. Detailed DATA and Monte Carlo (MC) comparisons were done in order to test reliability of the detector simulation. There is reasonable agreement between DATA and MC. The ratio of deep inelastic neutral-current (NC) to the deep inelastic (DIS) charged-current(CC) $\nu_{\mu}$ interactions was measured to be frac{NC_{dis}}{CC_{dis}}=0.350\pm0.003$. This measurement was compared with the previous measurements. Based on three double charm decays found in NC interactions we measured the ratio of double charm cross-section in NC $\nu_{\mu}$ interactions to be \[ \frac{\sigma (c\bar{c}\nu_\mu)}{\sigma_{NC}}=(3.37^{+3.06}_{-2.51}(stat.)\pm 0.51(syst.))\times 10^{-3}. \] One double charm decay has been observed in CC $\nu_{\mu}$ interactions the upper limit on associated charm production in $\nu_{\mu}$ CC interaction has been found to be \[ \frac{\sigma c\bar{c}\mu^{-})}{\sigma_{CC}}<9.69 \times 10^{-4}. \] at 90\% C.L.

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...
Antineutrino charm production and pentaquark search in the chorus experiment
Köse, Umut; Güler, Ali Murat; Department of Physics (2006)
During the years between 1994 and 1997, the emulsion target of the CHORUS experiment was exposed to the wide band neutrino beam of the CERN SPS of 27 GeV average energy collecting about 106 neutrino interactions. A measurement of induced charm production and search for anticharmed pentaquark ( 0 c ) have been performed by using the presence of a 6% component in the beam. By requiring a positive muon charge as determined by the CHORUS muon spectrometer, 46 -induced charm events were observed with ...
Measurement of topological muonic branching ratios of charmed hadrons produced in neutrino-induced charged-current interactions
Kayis-Topaksu, A; et. al. (2005-10-20)
From 1994 to 1997, the emulsion target of the CHORUS detector was exposed to the wideband 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 based on the data acquired by new automatic scanning systems; 2013 charm-decay events were selected by a pattern recognition program. They were confirmed as decays through visual inspection. Based on these events, the effective branch...
