Abstract
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 p t,veto ≳ 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.

Branching to bb, which is very difficult experimentally because of the large gg → bb background, is the branching to W W
We study the impact of finite mass effects due to top and bottom loops in the jet-veto distribution for Higgs production
In ref. [3], it was pointed out that the jet-veto is within the scope of the resummation program CAESAR [4] and a next-to-leading logarithmic (NLL) resummation matched to next-to-next-to-leading order (NNLO) results was presented
Summary
We consider the production of a Higgs boson accompanied by an arbitrary number of extra. When the transverse momentum of the emitted gluons is larger than the mass of the virtual quarks, new logarithms of the ratio of the two scales appear in the perturbative expansion Such logarithms are not proportional to the Born cross section, and in the following we will refer to them as non-factorizing terms. These logarithms are not proportional to the Born amplitude in eq (2.10), meaning that soft radiation does not factorize in the regime m2 ≪ p2t Since this fact questions the basis of our resummation approach, we devote the section to the calculation of these non-factorizing corrections to lowest order in perturbation theory
