General Mass Scheme for Jet Production in DIS

TL;DR

This paper introduces a new method for calculating jet production cross sections in deep inelastic scattering at NLO, incorporating heavy quark effects consistently using an extended dipole subtraction scheme compatible with the ACOT factorization.

Contribution

It extends the dipole subtraction method to include all initial state splittings with heavy quarks, enabling NLO calculations within the ACOT scheme.

Findings

Successfully recovers the ACOT result for heavy quark structure functions

Provides a consistent framework for NLO DIS jet calculations with heavy quarks

Extends existing subtraction methods to heavy quark initial states

Abstract

We propose a method for calculating DIS jet production cross sections in QCD at NLO accuracy with consistent treatment of heavy quarks. The scheme relies on the dipole subtraction method for jets, which we extend to all possible initial state splittings with heavy partons, so that the Aivazis-Collins-Olness-Tung massive collinear factorization scheme (ACOT) can be applied. As a first check of the formalism we recover the ACOT result for the heavy quark structure function using a dedicated Monte Carlo program.
