The dataset collected by the LHCb collaboration during Run 1 and Run 2 has played a major role in the progress of charm physics. For Run 3 of the LHC, the LHCb detector was upgraded to operate at higher instantaneous luminosities. This talk presents the first results obtained with early Run 3 data, measuring the production asymmetries of $D^0$, $D^+$, and $D_s^+$ charm and anticharm mesons in...
Meson decays offer a powerful probe for studying Axion-Like Particles (ALPs). In this talk, I will present our recent phenomenological analysis exploring ALP production in these decays, reviewing the current bounds across different channels. For this study, we systematically include hadronic ALP decays alongside a comprehensive set of ALP signatures: invisible, prompt, and displaced decays. We...
Electric dipole moments (EDMs) provide strong bounds on the CP structure of many New Physics (NP) scenarios. In this work, we study the charm Chromo-EDM (CEDM) within a new light scalar singlet with top-quark Flavour-Changing Neutral Current (FCNC) interactions. Such scalar singlet appears naturally in many well-motivated NP scenarios, such as the composite Higgs models. Unlike the Higgs boson...
