TL;DR
HNNLO is a Monte Carlo program that calculates Higgs boson production cross sections at hadron colliders up to NNLO in QCD, including various decay modes and customizable cuts.
Contribution
It provides a new computational tool for precise Higgs production predictions at NNLO, incorporating multiple decay channels and flexible event selection.
Findings
Accurate cross section calculations up to NNLO in QCD.
Inclusion of multiple Higgs decay modes.
User-defined cuts for detailed phenomenological studies.
Abstract
We consider Higgs boson production through gluon--gluon fusion in hadron collisions. We present a numerical program that computes the cross section up to NNLO in QCD perturbation theory. The program includes the decay modes H->gamma-gamma, H->WW->lnulnu, H->ZZ->4leptons, and allows the user to apply arbitrary cuts on the momenta of the partons and of the photons or leptons that are produced in the final state.
