摘要：

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