D Production Asymmetry at the LHC from Heavy-Quark Recombination
Abstract
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 non-perturbative parameters, our calculated results can reproduce those obtained at LHCb. We find Ap ~ -1% when integrated over 2.0 GeV < pT < 18 GeV and 2.2< eta <4.75, which agrees with Ap=-0.960.260.18% as measured by LHCb. Furthermore, the calculated distributions in eta and pT agree reasonably well with those obtained at LHCb.
