In this talk I review the status of new physics in $b\to c \tau \nu$ transitions in the EFT framework of dimension-six operators. The fit results, including the recent measurement of $F_L(D^*)$, are presented for all one- and two-dimensional scenarios resulting from the tree level exchange of a single new particle. Particular emphasis is put on the constraint from the $B_c \to \tau \nu$ decay...

Decay modes with two oppositely charged leptons of different flavor correspond to lepton flavor violating (LFV) decays and are essentially forbidden in the Standard Model (SM) because they can occur only through lepton mixing. Decay modes with two leptons of the same charge are lepton-number violating (LNV) decays and are forbidden in the SM. Hence, decays of the form $D^0 \to hh'll’$ provide...

We present a Bayesian analysis of the implications for new physics in semileptonic b → s transitions after including new measurements of RK at LHCb and new determinations of RK∗ and RK∗+ at Belle. We perform global fits with 2, 4, and 8 input Wilson coefficients, plus one CKM nuisance parameter to take into account uncertainties that are not factorizable. We infer the 68% and 95.4% credibility...

There are four models of tree-level new physics (NP) that can
potentially simultaneously explain the $b \to s \mu^+\mu^-$ and $b \to
c \ell^- {\bar\nu}$ anomalies. They are the S3, U3, and U1
leptoquarks, and a triplet of standard-model-like vector bosons
(VBs). In this talk, I describe an analysis of these models with
general couplings. We find that, even in this most general case,...

Very large CP asymmetries in decays of B mesons to final states containing three charged particles have been observed and attracted much interest. We present new results from a Dalitz plot analysis of B->3pi using a data sample corresponding to an integrated luminosity of 3 fb-1 of pp collisions recorded by the LHCb detector. Significant CP violation from different sources (S-wave, D-wave,S-P...

We study the renormalization effects on electric dipole moments in the models with new electroweakly interacting massive fermions. The electric dipole moments are generated by the effective operators which arise from integrating out heavy particles at some scale in the models. We give the renormalization group equation for the Wilson coefficients of the effective operators from the scale where...

At present, there are discrepancies with the predictions of the SM in ${\bar B} \to D^{(*)} \ell^- {\bar\nu}$ decays, suggesting the presence of new physics (NP) in $b \to c \tau^- {\bar\nu}$. Various NP models have been proposed to explain the data. In this talk, I discuss how the measurement of CP-violating observables in ${\bar B} \to D^* \ell^- {\bar\nu}$ can be used to differentiate the...

CP violations have been established in beauty mesons basically in two-body states, but so far not for charm mesons. Yet it is crucial to measure CP asymmetries in many-body final states -- including for beauty & charm baryons!
Non-perturbative QCD gives large impact. [Of course, these results do not help us to understand the matter vs. anti-matter in our Universe.]

Light-front wavefunctions obtained from holographic AdS/QCD are used to obtain the distributions amplitudes for light mesons.

We examine the sensitivity of electric dipole moments (EDMs) as precision observables for new $CP$-violating physics in a dark sector. Assuming that the dominant mediation channel is via one or more of the vector, Higgs or neutrino portals, we examine the leading EDM contributions. The dominant contributions arise at two-loop order, and EDMs can provide sensitivity to portal couplings that is...

This talk will focus on the latest results from ATLAS, such as rare processes: B^0_s -> mu mu and B^0 -> mu mu; and CPV in Bs to Jpsi Phi.

The LHCb experiment has reported discrepancy of $(2.2-2.4)\sigma$ in the $\mu/e$ ratio of $\bar B \to \bar K^* l^+ l^-$ process, $R_{K^*}$, which reinforce the hints of lepton nonuniversality observed in $B^+ \to K^+ l^+ l^-$ process. We investigate the analogous lepton non-universaity ratios and other asymmetries in $B \to K_1 l^+ l^-$ and $B_s \to \phi l^+ l^-$ processes both in model...

Testing the couplings of the Higgs boson to leptons is important to
understand the origin of lepton masses. The talk presents cross section
measurements in Higgs boson decays to two tau leptons, as well as a search
for Higgs boson decays to two muons. Both analyses are based on pp collision
data collected at 13 TeV.
