Abstract We investigate the inverse moment of the B s -meson light-cone distribution amplitude (LCDA), denoted as λ B s $$ {\lambda}_{B_s} $$ and defined within the heavy quark effective theory, through the calculation of B s → η s form factors.

Abstract We study the B ¯ → D D ∗ ℓ − ν ¯ ℓ $$ \overline{B}\to D\left({D}^{\ast}\right){\ell}^{-}{\overline{\nu}}_{\ell } $$ decays based on the up-to-date available inputs from experiments and the lattice. First, we review the standard

We constrain the inverse moment of the B-meson light-cone distribution amplitude (LCDA), λB in heavy quark effective theory, using form factor estimates from Lattice QCD collaboration. The estimation of the parameter λB has, until now, relied solel

Abstract We have extracted the ratio |V ub |/|V cb | from a combined study of the available inputs on B ¯ → π ρ ω ℓ − ν ¯ ℓ $$ \overline{B}\to \left(\pi, \rho, \omega \right){\ell}^{-}{\overline{\nu}}_{\ell } $$ and B ¯ B ¯ s → D

Abstract After incorporating all the available experimental data and the most up-to-date Lattice and light cone sum rule (LCSR) inputs on the form factors, we analyze the exclusive b → uℓν ℓ and b → dℓℓ decays simultaneously. We have ext

Abstract To extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V ub |, we have re-analyzed all the available inputs (data and theory) on the B → πℓν decays including the newly available inputs on the form-factors from light cone sum ru

We perform a data-driven analysis of new physics (NP) effects in exclusive b→sℓ+ℓ− decays in a model-independent effective theory approach with dimension six operators considering scalar, pseudo-scalar, vector and axial-vector operators with

Women comprise around 15% of admissions to provincial correctional institutions in Canada. Women in custody are known to have a high prevalence of mental health concerns, but little is known about how those referred to mental health services compare
