A bstract The “Cabibbo Angle Anomaly”(CAA) originates from the disagreement between the
CKM elements V ud and V us extracted from superallowed beta and kaon decays …

A bstract We study the effective field theory sensitivity of an LHC analysis for the τν final state
with an associated b-jet. To illustrate the improvement due to the b-tagging, we first recast …

We perform an analysis of the b→ c τ ν data, including R (D (⁎)), R (J/ψ), P τ (D⁎) and
FLD⁎, within and beyond the Standard Model (SM). We fit the B→ D (⁎) hadronic form …

A bstract At present, the measurements of\({R} _ {D^{\left (\ast\right)}}\) and RJ/ψ hint at new
physics (NP) in\(b\to c {\tau}^{-}\overline {v}\) decays. The angular distribution of\(\overline …

In recent years, several deviations from the Standard Model predictions in semileptonic
decays of B-meson might suggest the existence of new physics which would break the …

A bstract In\({\Lambda} _b^ 0\to {\Lambda} _c^{+}\left (\to {\Lambda}^ 0 {\pi}^{+}\right){\tau}^{-
}{\overline {v}} _ {\tau}\) decay, the solid angle of the final-state particle τ− cannot be …

We use the framework of asymptotically safe quantum gravity to derive predictions for scalar
leptoquark solutions to the b → sb→ s and b → cb→ c flavor anomalies. The presence of an …

A bstract The measurements carried out at LEP and SLC projected us into the precision era
of electroweak physics. This has also been relevant in the theoretical interpretation of LHCb …

We benefit from a recent lattice determination of the full set of vector, axial and tensor form
factors for the Λ b→ Λ c*(2595) τ ν¯ τ and Λ c*(2625) τ ν¯ τ semileptonic decays to study the …

A bstract For a general H b→\({H} _c\tau {\overline {\nu}} _ {\tau}\) decay we analyze the role
of the τ polarization vector\({\mathcal {P}}^{\mu}\) in the context of lepton flavor universality …
