Andrii Verbytskyi24/04/2013, 14:00Heavy FlavoursTalk in Parallel Session at DIS2013The production of the excited charm mesons D_1(2420) and D*_2(2460) in ep collisions has been measured with the ZEUS detector at HERA using an integrated luminosity of 373 pb-1. The masses of the neutral and charged states, the widths of the neutral states, and the helicity parameter of D_1(2420)^{0} were determined and compared withother measurements and with theoretical...Go to contribution page

Ewald Paul24/04/2013, 14:20Heavy FlavoursTalk in Parallel Session at DIS2013The production of D*, D+, D0, Ds and Lambda_c charm hadrons and their antiparticles in ep scattering at HERA was studied with the ZEUS detector using the full HERA II data set. The measurement has been performed in the photoproduction regime. The fractions of c quarks hadronising as a particular charm hadron, f(c -> D, Lambda_c), were derived in the visible kinematic range.Go to contribution page

Shima Shimizu (Kobe University (JP))24/04/2013, 14:40Heavy FlavoursTalk in Parallel Session at DIS2013A measurement of the flavour composition of dijet events produced in pp collisions at 7 TeV using the ATLAS detector is presented. Six possible combinations of light, charm and bottom jets are identified in the dijet events, where the jet flavour is defined by the presence of bottom, charm or solely light flavour hadrons in the jet. The results agree with the predictions of leading- and...Go to contribution page

Antoni Szczurek (Institute of Nuclear Physics), Rafal Maciula (Institute of Nuclear Physics PAN)24/04/2013, 15:00Heavy FlavoursTalk in Parallel Session at DIS2013We discuss production of two pairs of $c \bar c$ in proton-proton collisions at the LHC. Both double-parton scattering (DPS) and single-parton scattering (SPS) contributions are included in the analysis. Each step of DPS is calculated within $k_t$-factorization approach, i.e. effectively including next-to-leading order corrections. The conditions how to identify the DPS contribution are...Go to contribution page

Nikolay ZOTOV (SINP, Moscow State University)24/04/2013, 15:20Heavy FlavoursTalk in Parallel Session at DIS2013The talk is based on the results of our publications [1]. First of all we show that the contribution from double parton scattering to the inclusive production of heavy meson pairs is comparable with the conventional single parton scattering mechanism at the LHC energy. Then we focus on the problem of disentangling the single (SPS) and double (DPS) parton scattering modes in the production...Go to contribution page

Andrew York (University of Tennessee (US))24/04/2013, 15:40Heavy FlavoursTalk in Parallel Session at DIS2013This talk presents quarkonium results, colllected in pp collisions at sqrt(s) = 7 TeV by the CMS collaboration, including the pT and rapidity differential prompt production cross-section of S-wave state quarkonia (J/psi, psi', Y(nS)), extending over a range of up to 100 GeV. We also present the B-hadron fraction in the charmonium system, differentially in pT. Given its powerful Silicon...Go to contribution page
