Abstract content

The asymmetry in the forward region production cross section of D± is calculated using the heavy quark recombination mechanism for pp collisions at 7 TeV. By suitable choices of four nonperturbative parameters, our calculated results can reproduce those obtained at LHCb. We find A p ∼ −1% when integrated over 2.0 GeV < p T < 18 GeV and 2.2 < η < 4.75, which agrees with A p = −0.96 ± 0.26 ± 0.18% as measured by LHCb. Furthermore, the calculated distributions in η and p T agree reasonably well with those obtained at LHCb. Predictions on production asymmetry of heavy baryons are also made in the same formalism.
