We study the resonant contributions in the process of B¯ 0→ K-π+ μ+ μ-with the K-π+
invariant mass square m K π 2∈[1, 5] GeV 2. Width effects of the involved strange mesons …

Abstract Recently, the LHCb Collaboration provided updated measurements for the lepton
flavour ratios\(R_K\) and\(R_ {K^*}\). The currently observed values align with the predictions …

A bstract The rare processes\({B} _c\to {D_ {(s)}^{\left (*\right)}} _J\mu\overline {\mu}\), where
D (*)(s) J stands for the final meson D* s0 (2317), D s1 (2460, 2536), D* s2 (2573), D* 0 …

We investigate the radiative process of Λ b→ Λ γ in the standard model as well as models
with one or two compact universal extra dimensions. Using the form factors entered to the …

A bstract Using form factors enrolled to the transition matrix elements and calculated via light-
cone QCD sum rules including next-to-leading order corrections in the strong coupling …

A bstract We obtain a lower limit on the compactification scale of extra dimension via
comparison of the branching ratio in the baryonic Λ b→ Λμ+ μ− decay channel recently …

In this article, we assume the two nonets of scalar mesons below and above 1 GeV are all
q¯ q states, and study the semi-leptonic decays B→ S ℓ− ν¯ ℓ, B→ S ℓ+ ℓ− and B→ S ν¯ ν …

The rare semileptonic B c→ D s* ℓ+ ℓ-decay is studied in the scenario of the universal extra
dimension model with a single extra dimension in which the inverse of the compactification …

A bstract A detailed study of the impact of New Physics (NP) operators with different Lorentz
structures, which are absent in the Standard Model Hamiltonian, on the B→\(K_2^{*}\)(1430) …

A bstract We study the radiative dileptonic B→ γl+ l− transition in the presence of a universal
extra dimension in the Applequist-Cheng-Dobrescu model. In particular, using the …
