test of the CKM paradigm, probing short distance scales beyond the reach of
the LHC. The main goal of the NA62 experiment at CERN is the measurement of
the K+ --> pi+ nu nu decay rate at 10% precision; the broader physics
programme includes searches for lepton flavour and lepton number violation
in kaon decays at record... -

New and recent results from the ATLAS programme of studies in EW physics with open beauty are presented, which includes studies of CP violation in the Bs sector and of FCNC in Bd and Bs.

FCNC processes are sensitive of NP contributions, in particular through additional electroweak loop amplitudes. The angular analysis of the decay of Bd -> K* mu mu for a number of angular coefficients are... -

Three key issues pertaining to the semi-leptonic RD(*) anomalies will be addressed here: 1) How robust are the SM predictions? 2) What are the model-independent collider signature of these anomalies? 3) What are some of the simplest BSM explanations for these?
In answer to 1) latest information from on and off the lattice will be critically examined to question, in particular the reliability...

The confirmation of excess in $R_{D^*}$ at the LHCb is an indication of lepton flavor non-universality. Various different new physics operators and their coupling strengths, which provide a good fit to $R_D$, $R_{D^*}$ and $q^2$ spectra, were identified previously. In this work, we try to find angular observables in $\bar{B} \to D^* \tau \bar{\nu}$ which enable us to... -

The semileptonic decays $B\to D^{(\ast)}\tau\nu$ have received lots of attention recently, due to an observed discrepancy between standard-model predictions and measurements. Experimentally, these processes are challenging due the fast decay of the tau lepton, which is indirectly observed through its decay products. From a theory perspective, the tau lepton is exactly what makes $B\to...

Effective field theories such as Heavy Quark Effective Theory (HQET) and Non Relativistic Quantum Chromo-(Electro-) dynamics NRQCD (NRQED) are indispensable tools for controlling the effects of the strong interaction. The increasing experimental precision requires the knowledge of higher dimensional operators. These operators are important to the evaluation of decay rates of the B-meson. We...

The LHCb has reported the observation of a resonancelike structure, the $P_c(4450)$, in the $J/\psi~p$ spectrum.
In our work, we discuss the feasibility of detecting this structure in $J/\psi$ photoproduction, e.g., in the measurement that has recently been approved for the CLAS12 experiment at JLab.
We take into account the experimental resolution effects, and perform a global fit to world...
