Tagging the Higgs boson decay to bottom quarks with colour-sensitive observables and the Lund jet plane

Luca Cavallini, Andrea Coccaro, Charanjit K. Khosa +6

We study the problem of distinguishing -jets stemming from the decay of a colour singlet, such as the Higgs boson, from those originating from the abundant QCD background. In pa…

Next-to-next-to-leading order event generation for production with decay

Silvia Zanoli, Mauro Chiesa, Emanuele Re +2

We consider the Higgsstrahlung process in hadronic collisions and present the computation of next-to-next-to-leading order predictions matched to parton showers for both production…

Leptoquark manoeuvres in the dark: a simultaneous solution of the dark matter problem and the anomalies

Geneviève Belanger, Aoife Bharucha, Benjamin Fuks +10

The measured branching fractions of -mesons into leptonic final states derived by the LHCb collaboration hint towards the breakdown of lepton flavour universality. In this work…

Transverse momentum dependent distributions in dijet and heavy hadron pair production at EIC

Rafael F. del Castillo, Miguel G. Echevarria, Yiannis Makris +1

We discuss the measurement of gluon transverse momentum distribution (TMD) in dijet and heavy hadron pair (HHP) production in semi-inclusive deep inelastic scattering. The factoriz…

Energy-momentum tensor in QCD: nucleon mass decomposition and mechanical equilibrium

Cédric Lorcé, Andreas Metz, Barbara Pasquini +1

We review and examine in detail recent developments regarding the question of the nucleon mass decomposition. We discuss in particular the virial theorem in quantum field theory an…

NNLO virtual and real leptonic corrections to muon-electron scattering

E. Budassi, C. M. Carloni Calame, M. Chiesa +5

The recently proposed MUonE experiment at CERN aims at providing a novel determination of the leading order hadronic contribution to the muon anomalous magnetic moment through the…

Multi Higgs production via photon fusion at future multi-TeV muon colliders

Mauro Chiesa, Barbara Mele, Fulvio Piccinini

Multi-TeV muon colliders promise an unprecedented potential for exploring the particle-physics energy frontier, and, at the same time, can probe with fantastic accuracy the precise…

Where do we stand with a 3-D picture of the proton?

Alessandro Bacchetta

We are on the way to obtaining multi-dimensional "pictures" of the proton. The field is bursting with activities, both from the theoretical and experimental side. A brief selection…

A spectator-model way to transverse-momentum-dependent gluon distribution functions

Alessandro Bacchetta, Francesco Giovanni Celiberto, Marco Radici +1

We present exploratory analyses of the 3D gluon content of the proton via a study of unpolarized and polarized gluon TMDs at twist-2, calculated in a spectator model for the parent…

Searching for pseudo Nambu-Goldstone boson dark matter production in association with top quarks

Ulrich Haisch, Giacomo Polesello, Stefan Schulte

Pseudo Nambu-Goldstone bosons (pNGBs) are attractive dark matter (DM) candidates, since they couple to the Standard Model (SM) predominantly through derivative interactions. Thereb…

Virtual Compton scattering at low energies with a positron beam

B. Pasquini, M. Vanderhaeghen

The Virtual Compton scattering (VCS) process at low energies explores the electromagnetic structure of the proton in terms of generalized polarizabilities (GPs). In the one-photon…

The gravitational form factor D(t) of the electron

Andreas Metz, Barbara Pasquini, Simone Rodini

The electron-graviton interaction can be described in terms of the gravitational form factors of the QED energy momentum tensor. Here we focus on the form factor D(t), and we exami…

TMDlib2 and TMDplotter: a platform for 3D hadron structure studies

N. A. Abdulov, A. Bacchetta, S. Baranov +35

A common library, TMDlib2, for Transverse-Momentum-Dependent distributions (TMDs) and unintegrated parton distributions (uPDFs) is described, which allows for easy access of common…

Revisiting the role of grooming in DIS

Yiannis Makris

We introduce a novel grooming procedure, which is an extension of the modified MassDrop tagging algorithm, tailored to the needs of deep inelastic scattering (DIS). The new algorit…

Energy-energy correlators in Deep Inelastic Scattering

Hai Tao Li, Yiannis Makris, Ivan Vitev

The energy-energy correlator (EEC) is an event shape observable which probes the angular correlations of energy depositions in detectors at high energy collider facilities. It has…
