Semi-Leptonic D_s^+(1968) Decays as a Scalar Meson Probe

, 2011
The unusual multiplet structures associated with the light spin zero mesons have recently attracted a good deal of theoretical attention. Here we discuss some aspects associated with the possibility of getting new experimental information on this topic ...

SCET sum rules for Λ b → Λℓ + ℓ − , Λγ decays

Journal of High Energy Physics
We construct light-cone sum rules for various types of effective form factors in the Λ b → Λℓ + ℓ − and Λ b → Λγ decays by analyzing vacuum-to-Λ b (or γ *-to-Λ b ) correlation functions with the light Λ-baryon interpolating current.

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.

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

Constraining |V cs | and physics beyond the Standard Model from exclusive (semi)leptonic charm decays

Journal of High Energy Physics
We study the available data on exclusive leptonic and semileptonic c → sℓ + ν decays within the Standard Model and beyond. Our analysis accounts for theory correlations between the relevant hadronic matrix elements through application of dispersive ...

Total decay rates of B mesons at NNLO-QCD

Journal of High Energy Physics
We update the Standard Model (SM) predictions for the lifetimes of the B +, B d and B s mesons within the heavy quark expansion (HQE), including the recently determined NNLO-QCD corrections to non-leptonic decays of the free b-quark.
