The final oscillation analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. Reconstruction algorithms of data extracted by electronic detectors were improved and the data recorded in the emulsion target were analysed by new automated scanning systems, allowing the use of a new method for event reconstruction in emulsion. CHORUS has applied these new techniques to the sample of 1996-1997 events for which no muons were observed in the electronic detectors. Combining the new sample with the data analysed in previous papers, the overall sensitivity of the experiment to the nu(tau) appearance is thus improved. In a two-neutrino mixing scheme, a 90% C.L. upper limit of sin(2)2 theta(mu tau) < 4.4 x 10(-4) is set for large Delta m(2), improving by a factor 1.5 the previously published CHORUS result.

First measurement of the cross section for top-quark pair production in proton-proton collisions at root s=7 TeV
Khachatryan, V.; et. al. (Elsevier BV, 2011-01-01)
The first measurement of the cross section for top-quark pair production in pp collisions at the Large Hadron Collider at center-of-mass energy root s = 7 TeV has been performed using a data sample corresponding to an integrated luminosity of 3.1 +/- 0.3 pb(-1) recorded by the CMS detector. This result utilizes the final state with two isolated, highly energetic charged leptons, large missing transverse energy, and two or more jets. Backgrounds from Drell-Yan and non-W/Z boson production are estimated from ...
Measurement of the W+W- and ZZ production cross sections in pp collisions at root s=8 TeV
Chatrchyan, S.; et. al. (Elsevier BV, 2013-04-01)
The W+W- and ZZ production cross sections are measured in proton-proton collisions at root s = 8 TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up to 5.3 fb(-1). The measurements are performed in the leptonic decay modes W+W- -> l'vl '' v and ZZ -> 2l2l', where l = e, mu and l'(l '') = e, mu, tau. The measured cross sections sigma (pp -> W+W-) =, 69.9 +/- 2.8 (stat.) +/- 5.6 (syst.) 3.1 +/- (lum.) pb and sigma (pp -> ZZ) = 8.4 +/- 1.0 (stat) +/- 0.7 (syst...
Leading order analysis of neutrino induced dimuon events in the CHORUS experiment
Kayis-Topaksu, A.; et. al. (Elsevier BV, 2008-07-21)
We present a leading order QCD analysis of a sample of neutrino induced charged-current events with two muons in the final state originating in the lead-scintillating fibre calorimeter of the CHORUS detector. The results are based on a sample of 8910 neutrino and 430 antineutrino induced opposite-sign dimuon events collected during the exposure of the detector to the CERN Wide Band Neutrino Beam between 1995 and 1998. The analysis yields a value of the charm quark mass of m(c) = (1.26 +/- 0.16 +/- 0.09) GeV...
Measurement of the t-channel single top-quark production cross section in pp collisions at root s=7 TeV with the ATLAS detector
Aad, G.; et. al. (Elsevier BV, 2012-10-31)
We report a measurement of the cross section of single top-quark production in the t-channel using 1.04 fb(-1) of pp collision data at root s = 7 TeV recorded with the ATLAS detector at the LHC. Selected events feature one electron or muon, missing transverse momentum, and two or three jets, exactly one of them identified as originating from a b quark. The cross section is measured by fitting the distribution of a multivariate discriminant constructed with a neural network, yielding sigma(t) = 83 +/- 4 (sta...
Measurement of prompt J/psi pair production in pp collisions at root s = 7 Tev
Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2014-09-01)
Production of prompt J/psi meson pairs in proton-proton collisions at root s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb(-1). The two J/psi mesons are fully reconstructed via their decays into mu(+)mu(-) pairs. This observation provides for the first time access to the high-transverse-momentum region of J/psi pair production where model predictions are not yet established. The total and differential cross sections are meas...
