New results on small-x resummation for splitting functions

Marco Bonvini, Stefano Frixione, Giovanni Stagnitto

We revisit the basic steps necessary to obtain next-to-leading-logarithmic accurate small- $x$ results for the DGLAP splitting functions, and their implementations within the HELL f…

Flavoured jet algorithms: a comparative study

Arnd Behring, Simone Caletti, Francesco Giuli +17

The accurate identification of heavy-flavour jets, those which originate from bottom or charm quarks, is crucial for precision studies of the Standard Model and searches for new ph…

Precision phenomenology at multi-TeV muon colliders

Stefano Frixione, Fabio Maltoni, Davide Pagani +1

Future lepton colliders, such as those based on linear $e^{+} e^{-}$ or circular $μ^{+} μ^{-}$ accelerators, are expected to attain centre-of-mass energies in the multi-TeV range. In this re…

A Simplified Model of Heavy Vector Singlets for the LHC and Future Colliders

Michael J. Baker, Timothy Martonhelyi, Andrea Thamm +1

We study a simplified model of two colourless heavy vector resonances in the singlet representation of $S U (2)_{L}$ , with zero and unit hypercharge. We discuss mixing with the Stand…

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 $e^{+} e^{-}$ collisions, at different centre-of-mass energi…

Les Houches guide to reusable ML models in LHC analyses

Jack Y. Araz, Andy Buckley, Gregor Kasieczka +10

With the increasing usage of machine-learning in high-energy physics analyses, the publication of the trained models in a reusable form has become a crucial question for analysis p…

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…

Charming-loop contribution to $B_{s} \to γ γ$ decay

Ilia Belov, Alexander Berezhnoy, Dmitri Melikhov

We present a detailed theoretical study of nonfactorizable contributions of the charm-quark loop to the amplitude of the $B_{s} \to γ γ$ decay. This contribution involves the $B$ -mes…

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…

Decay widths and mass spectra of single bottom baryons

H. García-Tecocoatzi, A. Giachino, A. Ramirez-Morales +3

We develop a Hamiltonian model that incorporates the spin, spin-orbit, and isospin interactions to determine the masses of the ground states of single-bottom baryons and their exci…

Goodness of fit by Neyman-Pearson testing

Gaia Grosso, Marco Letizia, Maurizio Pierini +1

The Neyman-Pearson strategy for hypothesis testing can be employed for goodness of fit if the alternative hypothesis is selected from data by exploring a rich parametrised family o…

Type-II Majoron Dark Matter

Carla Biggio, Lorenzo Calibbi, Toshihiko Ota +1

We discuss in detail the possibility that the ``type-II majoron'' -- that is, the pseudo Nambu-Goldstone boson that arises in the context of the type-II seesaw mechanism if the lep…

Collinear functions for QCD resummations

Stefano Catani, Prasanna K. Dhani

The singular behaviour of QCD squared amplitudes in the collinear limit is factorized and controlled by splitting kernels with a process-independent structure. We use these kernels…
