Analytical Expressions for the Hard-Scattering Production of Massive Partons
We obtain explicit expressions for the two-particle differential cross section $$E_c E_\kappa d\sigma (AB \to c\kappa X) /d\bb c d \bb \kappa$$ and the two-particle angular correlation function \break $$d\sigma(AB$$$ \to$$$ c\kappa X)/d\Delta \phi \, d\Delta y$$ 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 $$d\sigma(AB \to cX) /dy_c c_T dc_T $$ is also obtained and compared with the ALICE experimental data for charm production in $pp$ collisions at 7 TeV at LHC.
