Phenomenology of heavy-flavour jet angularities at hadron colliders

A

bstract

We compute resummed and matched predictions for jet angularities in hadronic Z +jet events, where the jet is initiated by a b -quark. The analysis is performed both with and without grooming the candidate jets using the SoftDrop algorithm. Mass effects are consistently included at both fixed-order and resummed levels. Our theoretical predictions also incorporate non-perturbative corrections from the underlying event and hadronization, implemented through parton-to-hadron transfer matrices extracted from dedicated Monte Carlo simulations with Sherpa. Finally, we compare results for b -jets with the ones from light-flavour jets, in order to quantify the impact of finite-mass effects.
