Anomalies in Hadronic $B \to V V$ Decays

Bhubanjyoti Bhattacharya, Marianne Bouchard, Alexandre Jean +2

Recently, a fit of charmless $B \to P P$ decays ( $B \in {B^{0}, B^{+}, B_{s}^{0}}$ , $P \in {π, K, η, η^{'}}$ ) to the latest data was performed under the assumption of flavour SU(3) symmet…

Isospin-based EWP-tree Relations

Bhubanjyoti Bhattacharya, Marianne Bouchard, Alexandre Jean +2

In 1998, it was shown that, if flavor SU(3) symmetry [SU(3) $_{F}$ ] is assumed in charmless $B \to P P$ decays ( $P$ is a light pseudoscalar meson), some reduced matrix elements involvi…

Investigating non-local contributions in $B_{s} \to ϕ ℓ ˉ ℓ$ including higher-twist effects

M. S. A. Alam Khan, Rusa Mandal, Praveen S Patil +1

We analyze the impact of higher-twist three-particle $B_{s}$ -meson light-cone distribution amplitudes (LCDAs) on the non-local form factors for the $B_{s} \to ϕ ℓ ˉ ℓ$ transiti…

Probing the inverse moment of $B_{s}$ -meson distribution amplitude via $B_{s} \to η_{s}$ form factors

Rusa Mandal, Praveen S Patil, Ipsita Ray

We investigate the inverse moment of the $B_{s}$ -meson light-cone distribution amplitude (LCDA), denoted as $λ_{B_{s}}$ and defined within the heavy quark effective theory, through the…

Constraining inverse moment of $B$ -meson distribution amplitude using Lattice QCD data

Rusa Mandal, Soumitra Nandi, Ipsita Ray

We constrain the inverse moment of the $B$ -meson light-cone distribution amplitude (LCDA), $λ_{B}$ in heavy quark effective theory, using form factor estimates from Lattice QCD colla…

Test of new physics effects in $B ˉ \to (D^{(*)}, π) ℓ^{-} ν ˉ_{ℓ}$ decays with heavy and light leptons

Ipsita Ray, Soumitra Nandi

We study the $B ˉ \to D (D^{*}) ℓ^{-} ν ˉ_{ℓ}$ decays based on the up-to-date available inputs from experiments and the lattice. First, we review the standard model (SM) predi…
