Phenomenology of heavy-flavour jet angularities at hadron colliders
Andrea Ghira, Lorenzo Mai, Simone Marzani +3
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…
The Lund -jet plane
Andrea Ghira, Simone Marzani, Gregory Soyez
We compute the primary Lund plane density for jets initiated by a massive () quark to single logarithmic accuracy in Quantum Chromodynamics (QCD). In order to capture mass effec…
Heavy Flavor Jet Substructure at Lepton Colliders
Prasanna K. Dhani, Oleh Fedkevych, Andrea Ghira
We provide a detailed analysis of event-shape observables, namely the energy correlation function and jet angularity, for heavy-flavor jets produced in electron-positron collisions…
Bridging massive and massless schemes for soft gluon resummation in heavy-flavour production in collisions
Andrea Ghira, Lorenzo Mai, Simone Marzani
Perturbative calculations for processes involving heavy flavours can be carried out using two approaches: the massive and the massless schemes. These schemes can also be combined t…
Heavy Flavour Jet Substructure
Prasanna K. Dhani, Oleh Fedkevych, Andrea Ghira +2
We present a comprehensive study of energy correlation functions and jet angularities for heavy-flavour QCD jets. In particular, we discuss the possibility of using these observabl…
Les Houches 2023: Physics at TeV Colliders: Standard Model Working Group Report
J. Andersen, B. Assi, K. Asteriadis +81
This report presents a short summary of the activities of the "Standard Model" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 12-30 June, 2023).
An improved description of charm fragmentation data
Matteo Cacciari, Andrea Ghira, Simone Marzani +1
We consider the fragmentation of heavy quarks into heavy-flavoured hadrons, specifically the production of charmed mesons in collisions, at different centre-of-mass energi…
On heavy-flavour jets with Soft Drop
Simone Caletti, Andrea Ghira, Simone Marzani
We study hadronic jets that are tagged as heavy-flavoured, i.e. they contain either beauty or charm. In particular, we consider heavy-flavour jets that have been groomed with the S…
A consistent resummation of mass and soft logarithms in processes with heavy flavours
Andrea Ghira, Simone Marzani, Giovanni Ridolfi
Perturbative calculations for processes that involve heavy flavours can be performed in two approaches: the massive scheme and the massless one. The former enables one to fully acc…
Soft resummation in processes with heavy quark: bridging the gap from 4-flavor to 5-flavor scheme
Andrea Ghira
In this work we present a new approach to threshold resummation in processes with heavy quarks. In particular we will focus on the differential decay rate of a color-singlet partic…
Non commutativity between massless and soft limit in processes with heavy quarks
Andrea Ghira
Processes involving heavy quarks can be computed in perturbation theory in two different ways: we can adopt a scheme in which the mass of the quark is considered only as a regulato…
Soft logarithms in processes with heavy quarks
Daniele Gaggero, Andrea Ghira, Simone Marzani +1
Observables involving heavy quarks can be computed in perturbative QCD in two different approximation schemes: either the quark mass dependence is fully retained, or it is retained…
