B ¯ → D ∗ ℓ ν ¯ $$ \overline{B}\to {D}^{\left(\ast \right)}\ell \overline{\nu} $$ branching ratios and evidence for isospin breaking in Υ(4S) decays

Journal of High Energy Physics
We introduce a new method for the determination of the ratio of production fractions R ± 0 = B Υ 4 S → B + B − / B Υ 4 S → B 0 B ¯ 0 $$ {R}^{\pm 0}=\mathcal{B}\left(\mathrm{Y}(4S)\to {B}^{+}{B}^{-}\right)/\mathcal{B}\left(\mathrm{Y}(4S)\to {B}^0 ...

Disentangling new physics in K → πν ν ¯ $$ K\to \pi \nu \overline{\nu} $$ and B → K K ∗ ν ν ¯ $$ B\to K\left({K}^{\ast}\right)\nu \overline{\nu} $$ observables

Journal of High Energy Physics
We investigate the possibility of disentangling different new physics contributions to the rare meson decays and through kinematic distributions in the missing energy .

Hyperon semileptonic decays in QCD sum rules

Journal of High Energy Physics
We investigate the hyperon semileptonic decays within the framework of QCD sum rules. The flavor SU(3) symmetry breaking effects are analyzed via the relevant form factors and corresponding branching fractions.

Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays

Journal of High Energy Physics
We perform a global analysis of |∆c| = |∆u| = 1 transitions using recent data on D 0 → μ + μ − , D + → π + μ + μ − , Λ c → p μ + μ − , and D 0 → π + π − μ + μ − decays, and work out constraints on new physics Wilson coefficients C 7 , 9 , 10 ′ $$ {C}_{7 ...
