B. Bailey et al., PRODUCTION OF A PROMPT PHOTON IN ASSOCIATION WITH A CHARM QUARK AT NEXT-TO-LEADING ORDER IN QCD, Physical review. D. Particles and fields, 54(3), 1996, pp. 1896-1907
A second order O(alpha(s)(2)) calculation in perturbative quantum chro
modynamics of the two particle inclusive cross section is presented fo
r the reaction p + (p) over bar --> gamma+ c + X for large values of t
he transverse momentum of the prompt photon and charm quark. The combi
nation of analytic and Monte Carlo integration methods used here to pe
rform phase-space integrations facilitates the imposition of photon is
olation restrictions and other selections of relevance in experiments.
Differential distributions are provided for various observables. Posi
tive correlations in rapidity are predicted.
