【 摘 要 】

We obtain explicit expressions for the two-particle differential cross section EcEKdσ(AB→cKX)/dcdk and the two-particle angular correlation function dσ(AB→cKX)/dφdy in the hard-scattering production of massive partons in order to exhibit the "ridge" structure on the away side in the hard-scattering process. The single-particle production cross section dσ(AB→cX)/dyccTdcT is also obtained and compared with the ALICE experimental data for charm production in pp collisions at 7 TeV at LHC.
