CP violation in the field of B physics is a crucial topic for exploring the quark sector and searching for New Physics, both for theorists and experimentalists. It manifests itself in various ways, and in this presentation we categorise decays according to their underlying dynamics, providing a roadmap to the study of CP violation in different classes of decay processes. Within this framework,...

Indirect searches for new physics at the LHC and future colliders rely on Effective Field Theories such as the SMEFT. However, recent studies indicate that global fits of Parton Distribution Functions (PDFs) can fully or partially absorb signs of new physics in the high-energy tails of HL-LHC measurements.

We study relativistic corrections to prompt $\psi(2S)$ and $J/\psi$ at high $P_T$ in hadron colliders. Our calculation employs leading-power factorization with Fragmentation Functions (FFs) computed in nonrelativistic QCD and evolved to next-to-leading-logarithmic accuracy. We extract constraints on the $\chi_c$ feeddown to the $J/\psi$ yield from the measured $\psi(2S)/J/\psi$ yield ratio....

Quarkonium production in hadronic collisions is a key observable for studying the interaction of heavy quarks with the nuclear medium.

Generalized Transverse Momentum Dependent parton distributions (GTMDs) can be accessed in ultraperipheral collisions (UPCs) and in photoproduction, which allows for a direct comparison of LHC and EIC data in the future, but not every GTMD observable at LHC has an analogous process at EIC or vice versa.

Transverse Momentum Dependent (TMD) parton densities are well-defined QCD operators, however their determination remains challenging due to the dominance of non-perturbative effects at low energy scales. As a consequence, the impact of phenomenological modeling is difficult to control and may lead to a misinterpretation of the information carried by experimental data.

Top anti-top production at LHC involves gluon fusion. Studying azimuthal correlations of top pairs depends on gluon spin distributions. Such distributions, at relatively low Q^2, will feed into gluon distribution contributions to electron nucleon and nucleus production of strange and charm hadrons. Established models of GPDs and TMDs will enable this connection to be made.
