Quark Masses and Resummation in Precision QCD Theory
arXiv:0707.2101 · doi:10.1103/PhysRevD.78.056001
Abstract
It is shown that amplitude-based, exact resummation tames the un-cancelled IR divergences at O(alpha_s^2) in initial state radiation in QCD with massive quarks. Implications for precision predictions for LHC physics are discussed.
