Description

We calculate the cross section for the inclusive hadroproduction of B mesons as a function of transverse momentum pT at next-to-leading order (NLO) in the general- mass variable-flavor-number scheme using realistic non-perturbative fragmentation functions that are obtained through a global fit to e+e- data from CERN LEP1 and SLAC SLC exploiting their universality and scaling violations. We find good agreement with recent p anti p data taken by the CDF Collaboration in run II at the Fermilab Tevatron. We also present comparisons with NLO results obtained in two other schemes.
