Abstract
We calculate the transverse-momentum (${p}_{T}$) distribution for the inclusive hadroproduction of $B$ mesons at intermediate values of ${p}_{T}$ at next-to-leading order (NLO) in a dedicated finite-mass scheme using realistic nonperturbative fragmentation functions that are obtained through a global fit to ${e}^{+}{e}^{\ensuremath{-}}$ data from CERN LEP1 and SLAC SLC exploiting their universality and scaling violations. We find that finite-mass effects moderately enhance the cross section, by about 20% at ${p}_{T}=2{m}_{b}$, and rapidly fade out with increasing value of ${p}_{T}$, so that the zero-mass prediction is reached. We also perform comparisons with recent $p\overline{p}$ data taken by the CDF Collaboration in run II at the Fermilab Tevatron and comment on the usefulness of the fixed-flavor-number scheme.
