Lepton Universality violation would represent a signal of physics beyond the Standard Model.
Semileptonic decays of beauty mesons into leptons of the third generation are of particular interest, since some anomalies have been observed in the measurement of their Branching Ratios.
In this talk I will illustrate the strategy and the perspectives of the measurement of $R(D^*) = \mathcal{B}(B^0...

In $B_s^0 \to D_s^{\mp} K^{\pm}$ decays $CP$ violation
in the interference between direct decay and decay after mixing
results in a time-dependent asymmetry of the decay rates.
From a measurement of this asymmetry five $CP$ observables can be determined,
which are themselves sensitive to the CKM angle $\gamma$.
The talk presents the flavour-tagged analysis of the Run I dataset...

The LHCb and Belle collaborations have recently reported some hints for New Physics in $b\to s\ell\ell$ transitions that, taken at face value, point to a large violation of flavor universality in the lepton sector. Motivated by them, I will present a model able to accommodate the experimental anomalies and, at the same time, address the flavor problem of the SM. The model is based on the idea...

Although our current understanding of neutrino physics succeeds to compile most of the data into a three neutrino mixing framework, there are still experimental anomalies that need to be explained. The Reactor Antineutrino Anomaly (RAA) was highlighted in 2011, when a new spectral prediction of reactor antineutrinos showed a 6% deficit in the counts of previous experiments. A possible...

In the Standard Model (SM) of particle physics, the branching fraction (BF) and effective lifetime ($\tau$) of the decay $B_s^{0} \to \mu^+ \mu^-$ have been calculated with high precision. Both observables are very sensitive to the existence of new particles entering the decay diagram. As such, they are prime candidates to search for signs of New Physics (NP) in flavour. Since the 80’s,...

Semileptonic decays of $B$ mesons involving low-mass charged leptons $e$ or $\mu$ are expected to be free of non-Standard Model contributions and therefore play a critical role in determinations of $\vert V_{ub} \vert$ and $\vert V_{cb} \vert$. Of all the CKM matrix parameters, $\vert V_{ub} \vert$ is the least precise and in most need of additional studies in order to constrain the apex of...

The SuperNEMO demonstrator, which is the first module of the SuperNEMO experiment,
is looking for the neutrinoless double beta decay 0$\nu\beta\beta$ in order to
unveil the nature of the neutrino. Its unique design, combining both tracking and
calorimetry techniques, provides essential topological information. Indeed,
fully reconstructing the event kinematics gives access to a variety of...
