QCD Predictions for Event-Shape Distributions in Hadronic Higgs Decays
arXiv:2202.07333 · doi:10.1007/JHEP06(2022)009
Abstract
We study the six classical event-shape observables in hadronic Higgs decays at next-to-leading order in QCD. To this end, we consider the decay of on-shell Higgs bosons to three partons, taking into account both the Yukawa-induced decay to -quark pairs and the loop-induced decay to two gluons via an effective Higgs-gluon coupling. The results are discussed with a particular focus on the discriminative power of event shapes regarding these two classes of processes.
