Quark Production

Heavy quark production in hard diffractive scattering is analyzed with evaluation of cross-sections and Monte-Carlo event generations. “Super hard” Pomeron, the existence of which was recently supported by the UA8 collaboration at CERN [Formula: see text] Collider [Formula: see text], is included by proposing a new method of determining Pomeron structures. Detection of (anti-)top quarks in the single diffractive processes is also mentioned.

Parton Scattering

In this paper, we estimate the double parton scattering (DPS) contribution for the heavy quark production in pA collisions at the LHC. The cross-sections for the charm and bottom production are estimated using the dipole approach, taking into account the saturation effects, which are important for high energies and for the scattering with a large nucleus. We compare the DPS contribution with the single parton scattering one and demonstrate that in the case of charm production, both are similar in the kinematical range probed by the LHC. Predictions for the rapidity range analyzed by the LHCb Collaboration are also presented. Our results indicate that the study of the DPS contribution for the heavy quark production in pPb collisions at the LHC is feasible and can be useful to probe the main assumptions of the approach.

A systematic study of the inclusive single heavy quark and heavy-quark pair production cross sections in pp collisions is presented for RHIC and LHC energies. We compare with existing data when possible. The dependence of the rates on the renormalization and factorization scales is discussed. Predictions of the cross sections are given for two different sets of parton distribution functions.

Quark Production

One may expect a large rate of events, in hadron-nucleus collisions at the LHC, with several pairs of heavy-quarks produced contemporarily by multiple parton interactions. We estimate the inclusive cross sections of [Formula: see text], [Formula: see text] and [Formula: see text] production in p–A collisions in the central and in the forward rapidity regions.

Abstract We present predictions for heavy-quark production at the Large Hadron Collider making use of the $$ \overline{\mathrm{MS}} $$ MS ¯ and MSR renormalization schemes for the heavy-quark mass as alternatives to the widely used on-shell renormalization scheme. We compute single and double differential distributions including QCD corrections at next-to-leading order and investigate the renormalization and factorization scale dependence as well as the perturbative convergence in these mass renormalization schemes. The implementation is based on publicly available programs, MCFM and xFitter, extending their capabilities. Our results are applied to extract the top-quark mass using measurements of the total and differential $$ t\overline{t} $$ t t ¯ production cross-sections and to investigate constraints on parton distribution functions, especially on the gluon distribution at low x values, from available LHC data on heavy-flavor hadro-production.
