Quark masses in Higgs production with a jet veto

Abstract

We study the impact of finite mass effects due to top and bottom loops in the jet-veto distribution for Higgs production. We discuss the appearance of non-factorizing logarithms in the region pt > m_b. We study their numerical impact and argue that these terms can be treated as a finite remainder. We therefore detail our prescription for resumming the jet-vetoed cross section and for assessing its uncertainty in the presence of finite mass effects. Resummation for the jet-veto, including mass effects, has been implemented in the public code JetVHeto.

32 pages, 13 figures, 4 tables. Version published in JHEP. A few references added. Added appendix with study of the Higgs transverse momentum distribution in the presence of mass effects. A new release of the JetVHeto code (http://jetvheto.hepforge.org/) implements the results of this article
