28 Jan 2013 | | Abstract: | In the framework of the k_T-factorization approach, the production of prompt
photons in association with a heavy (charm or beauty) quarks at high energies
is studied. The consideration is based on the O(alpha alpha_s^2) off-shell
amplitudes of gluon-gluon fusion and quark-(anti)quark interaction
subprocesses. The unintegrated parton densities in a proton are determined
using the Kimber-Martin-Ryskin prescription. Our numerical predictions are
compared with the D0 and CDF experimental data. Also we extend our results to
LHC energies. | | Source: | arXiv, 1301.6515 | | Services: | Forum | Review | PDF | Favorites | |
