Light scalars in semi-leptonic decays of heavy quarkonia

, 2012
We study the mechanism of production of the light scalar mesons in the $D_s^+\to\pi^+\pi^- e^+\nu$ decays: $D_s^+\to s\bar s e^+\nu\to [\sigma(600)+f_0(980)] e^+\nu\to\pi^+\pi^- e^+\nu$, and compare it with the mechanism of production of the light ...

Heavy quark symmetry behind b → c semileptonic sum rule

Journal of High Energy Physics
Lepton flavor universality violations in semileptonic b → c transitions have garnered attention over a decade. For $${R}_{{H}_{c}}={\text{BR}}\left({H}_{b}\to {H}_{c}\tau {\overline{\nu }}_{\tau }\right)/{\text{BR}}\left({H}_{b}\to {H}_{c}{\ell ...

Extractions of |V ub |/|V cb | from a combined study of the exclusive b → u c ℓ − ν ¯ ℓ $$ b\to u(c){\ell}^{-}{\overline{\nu}}_{\ell } $$ decays

Journal of High Energy Physics, 2023
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 ∗ D s ∗ ℓ − ν ¯ ℓ ℓ = μ or e ...

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.

Hints of R-parity violation in B decays into $\tau \nu$

, 2013
In this article we show that the recently observed enhanced semi-leptonic and leptonic decay rates of the B meson into \tau \nu modes can be explained within the frame work of R-parity violating (RPV) MSSM.

Constraining the mixing matrix for Standard Model with four generations: time dependent and semi-leptonic CP asymmetries in $B_d^0$, $B_s$ and $D^0$

, 2010
Using existing experimental information from K, B and D decays as well as electroweak precision tests and oblique parameters, we provide constraints and correlations on the parameters of the 4X4 mixing matrix for the Standard Model with four generations (
