    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...

    Rare Decays of Hadrons and Leptons
    Contributed Oral
    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...

    Heavy hadron production is well-suited as a benchmark process for understanding QCD. While b-quark production properties can be estimated within perturbative QCD, the subsequent fragmentation into a b hadron is a non-perturbative process and cannot be calculated from the first principles. Our understanding of fragmentation functions and fractions thus relies solely on experimental input....

    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,...

    We study the renormalization effects on electric dipole moments in the models with new electroweakly interacting massive fermions.

    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.

    Time-dependent CP-violation measurements of beauty mesons allow the determination of the mixing-induced CP-violating phases phi_s and beta. The measurement of the phase phi_s in the Bs-Bsbar system is one of the key goals of the LHCb experiment due to the sensitivity to physics beyond the Standard Model (BSM). The CP-violating phase is of interest in penguin dominated b->s transitions, in...

    CP Violation in Hadrons and Leptons
    Contributed Oral
    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.]
