D-meson production at large hadron collider in the regge limit of QCD

Abstract

We study the inclusive production of $D^0$, $D^+$, $D^{\star+}$, and $D_s^+$ mesons in proton-antiproton collisions at the Tevatron and in proton-proton collisions at LHC at leading order in the parton Reggeization approach endowed with universal fragmentation functions fitted to $e^+e^-$ annihilation data from CERN LEP1. We have described $D$-meson transverse momentum distributions measured in the central region of rapidity by the CDF Collaboration at Tevatron ($|y|
