Comparison of approximate to exact next-to-next-to leading order corrections for Higgs and pseudoscalar Higgs boson production
arXiv:hep-ph/0307215
Abstract
Recently obtained NNLO exact corrections for Higgs and Pseudoscalar Higgs boson production in hadron colliders are compared with approximate ones. As shown before, it is found that there is a range of a proper variable where these corrections differ little.
