High energy resummation for rapidity distributions

TL;DR

This paper extends high-energy resummation techniques to rapidity distributions at leading logarithmic accuracy, applying it to Higgs production via gluon fusion and analyzing finite top mass effects.

Contribution

It introduces a generalized resummation method for rapidity distributions and tests it on Higgs production, including finite top mass corrections.

Findings

Resummation reproduces known fixed-order results.

Finite top mass corrections are estimated at NLO.

Method applicable to other processes at high energies.

Abstract

We discuss the generalisation of high-energy resummation to rapidity distributions to leading logarithmic accuracy. We test our procedure applying it to Higgs production in gluon-gluon fusion both with finite top mass and in the infinite mass limit. We check that they reproduce the known results at fixed order and we estimate finite top mass corrections to the NLO distribution.
