Abstract
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.
