Using improved theoretical calculations of the decay form factors in the Light Cone-QCD sum rule approach, we investigate the decay rates, dilepton invariant mass spectra and the forward-backward (FB) asymmetry in the decays B → (K, K ∗ )l + l − (l ± = e ± , µ ± , τ ± ) in the standard model (SM) and a number of popular variants of the supersymmetric (SUSY) models. Theoretical precision on the differential decay rates and FB-asymmetry is estimated in these theories taking into account various…

Motivated by recent experimental results on $ R_{K^{(*)}}$ and $\mathcal {P}^{\prime }_{5}$ in B → K(∗)l+l− and the latest improved measurement result in Λb →Λl+l− processes. We will investigate
The asymmetries of the $B \to K^* \mu^+ \mu^-$ decay and the search of new physics beyond the Standard Model
In this paper, we compute the forward-backward asymmetry and the isospin asymmetry of the $B \to K^* \mu^+ \mu^-$ decay. The $B \to K^*$ transition form factors (TFFs) are key components of the

The $B\rightarrow K_{2}^{\ast}(1430)l^{+}l^{-}$ $(l = \mu, \tau)$ decays are analyzed in the standard model (SM) extended to fourth generation of quarks (SM4). The decay rate, forward–backward
New Physics Effects on Rare Decays B+u → π+ℓ+ℓ−, ρ+ℓ+ℓ− in a Top Quark Two-Higgs-Doublet Model
Using the form factors from light-cone sum rules, we study the branching ratios and forward-backward asymmetries (FBAs) of the exclusive decays B+u → π+l+l− and B+u → ρ+l+l− (l = e,μ) in the standard
Analysis of neutral Higgs-boson contributions to the decays B s → l + l − and B ¯ → Kl + l −
We report on a calculation of Higgs-boson contributions to the decays B_s -> l^+l^- and B -> K l^+l^- (l=e, mu) which are governed by the effective Hamiltonian describing b -> s l^+ l^-. Compact
Search for Lepton Flavor Non-universality with B→ (K, K*) τ+τ- Decays
The decay modes of B meson consisting tau leptons as final state particle are seemed to be the key feature for searching new physics. As the experimental measurements for b → sτ+τ− processes are
Flavor-conserving CP phases in supersymmetry and implications for exclusive B decays
We study rare exclusive B decays based on the quark-level transition b->s(d)l^+l^-, where l=e or mu, in the context of supersymmetric theories with minimal flavour violation. We present analytic

The scaling predictions of the heavy quark effective theory are used to extract the necessary form factors from fits to various combinations of data, and it is found that integrated decay rates are not very sensitive to the forms chosen.
Phenomenological profiles of the inclusive hadron spectra in the decay B ---> X(s) lepton+ lepton-

Exclusive non-leptonic decays ofD-,Ds- andB-mesons
AbstractRecent experimental results onD-,Ds- andB-decays are interpreted on the basis of the valence quark model. For nonleptonic decays generally good results are obtained using factorization with
