Quark masses in Higgs production with a jet veto

TL;DR

This paper investigates how finite top and bottom quark mass effects influence the jet-veto distribution in Higgs production, proposing a method to resum these effects and quantify uncertainties.

Contribution

It introduces a new prescription for resumming jet-vetoed cross sections including finite quark mass effects, implemented in the JetVHeto code.

Findings

Finite mass effects can be treated as a finite remainder in resummation.

Non-factorizing logarithms appear for pt > m_b and are numerically significant.

The resummation method with mass effects is implemented in JetVHeto.

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.
