On the impact of meson mixing on B s → ϕee angular observables at low q 2

Journal of High Energy Physics, 2023
Decays based on the b → sγ transition are expected to yield left-handed photons in the Standard Model, but could be particularly sensitive to New Physics contributions modifying the short-distance Wilson coefficients C $$ \mathcal{C} $$ 7 and C ...

Radiative semileptonic decays of beautiful hadrons

Journal of High Energy Physics
We derive predictions for the hadronic matrix elements of radiative semileptonic decays of beautiful hadrons within Heavy Quark Effective Theory (HQET), relevant for future measurements at Belle II and LHCb.

Semileptonic tau decays beyond the Standard Model

Journal of High Energy Physics, 2022
Hadronic τ decays are studied as probe of new physics. We determine the dependence of several inclusive and exclusive τ observables on the Wilson coefficients of the low-energy effective theory describing charged-current interactions between light quarks

Rare semi-leptonic B meson decays [PDF]

, 2014
In this thesis, novel corrections to B → X˦ and B → Xl+l- decays, where X is a pseudoscalar or vector meson, are presented. These are the chromomagnetic matrix element, weak annihilation in a general four-quark operator basis and a long-distance charm ...

The kaon semileptonic form factor with near physical domain wall quarks

, 2013
We present a new calculation of the K → π semileptonic form factor at zero momentum transfer in domain wall lattice QCD with N f = 2+1 dynamical quark flavours. By using partially twisted boundary conditions we simulate directly at the phenomenologically

A first study of the semi-leptonic decay of the Λ baryon [PDF]

Nuclear Physics B - Proceedings Supplements, 1997
We present the preliminary results of the first Lattice study of the baryonic Isgur and Wise function obtained from the matrix element of the weak current between $Λ$-baryon external states. Its dependence on the heavy and light quark masses is studied. Some result on the semi-leptonic decay $Λ_b\toΛ_c +lν$ are given.
