Description

We describe calculations of cc production to next-to-next-to-leading order (NNLO) and next-to-next-to-leading logarithm (NNLL) near threshold in pp and π-p interactions. We study the relevance of these calculations for existing cc total cross section data by examining their sensitivity to partonic threshold kinematics, their convergence properties and scale dependence.
