Discrepancies between experimental measurements and Standard Model predictions in B-meson decays, especially in lepton flavor universality ratios like $R_{D^{(*)}}$, $R_{J/\psi}$ and branching ratios for processes like $B\rightarrow K^*\nu\bar{\nu}$, suggest possible new physics (NP). In this study, we use an effective field theory framework, assuming NP effects only affect a single generation...
The impact of earth's gravity on neutral mesons dynamics is analyzed. The main effect of a Newtonian potential is to couple the flavor oscillations with the quarks zitterbewegung oscillations. This coupling is responsible of the observed CP violations (CPV) in the three types of experiments: (i) indirect violation in the mixing, (ii) direct violation in the decay to one final state and (iii)...
Hyperiso is a refactored and expanded version of the flavour code SuperIso allowing for efficient calculations of flavour observables. While SuperIso was dedicated to SM, THDM and several SUSY models, Hyperiso now implements a transparent interface with MARTY (a public tool to perform
analytical QFT calculations) to extend SuperIso’s observable calculation routines to generic BSM scenarii....
The search for a non-zero electric dipole moment (EDM) of the muon is a sensitive tool to test the Standard Model, as it would indicate a further violation of the charge-parity (CP) symmetry. The current best upper limit, established by the E821 experiment at BNL, is $d_\mu < 1.8 \times 10^{-19} \: e \cdot \text{cm}$ at 95% of confidence level. The forthcoming $\mu$EDM experiment at PSI aims...
The ALADDIN experiment at the LHC aims to measure the electromagnetic dipole moments of charm baryons, a powerful probe of physics within and beyond the Standard Model. Utilizing the phenomenon of particle channeling in bent crystals and a novel detector setup, ALADDIN overcomes challenges posed by short-lived particles, enabling precise spin-precession measurements. This initiative not only...
The LHCb experiment is playing a leading role in the study of rare and forbidden decays of charm hadrons, which are sensitive to new interactions beyond the Standard Model. The latest searches for FCNC-mediated processes and asymmetry measurements in final states with two leptons are presented.
Hadronically decaying tau leptons are a challenging signature to study given it can be mimicked by quark and gluon jets, electrons, or muons. The identification of this signature via a convolutional neural network performed by CMS during the LHC Run 2 brought a massive improvement with respect to previous strategies. To further improve the identification and reconstruction of hadronic decays...
