We study the exclusive rare decay B → k ̄ l l. We calculate the relevant form factors within a
relativistic constituent quark model, for the first time without employing the impulse …

A bstract We perform a comprehensive study of the impact of new-physics operators with
different Lorentz structures on CP-violating observables involving the b→ sμ+ μ− transition …

The weak decays of Λ b→ Λ+ γ and Λ b→ Λ+ l+ l− are investigated in the standard model
using the light-cone sum-rule approach. The higher-twist distribution amplitudes of the Λ …

The reaction γ p→ π 0 γ′ p has been measured with the TAPS calorimeter at the Mainz
Microtron accelerator facility MAMI for energies between s= 1221–1331 M e V. The cross …

The weak decays of Λ b→ Λ l+ l-(l= e, μ) are investigated in the minimal supersymmetric
standard model (MSSM) and also in supersymmetric (SUSY) SO (10) grand unified models …

Using the most general, model independent form of the effective Hamiltonian, the exclusive
rare baryonic Λb→ Λℓ+ ℓ−(ℓ= μ, τ) decay is analyzed. We study the sensitivity of the …

We present a model independent analysis of Λ baryon polarizations in the Λ b→ Λ l+ l−
decay. The sensitivity of the averaged Λ polarizations to the new Wilson coefficients is …

Abstract We discuss B→ X s γ decay in both constrained and unconstrained supersymmetric
models with explicit CP violation within the minimal flavor violation scheme by including tan …

The general analysis of lepton polarization asymmetries in rare B→ K∗ ℓ+ ℓ− decay is
investigated. Using the most general, model independent effective Hamiltonian, the general …

Decay rate and forward–backward asymmetries in B→ K1l+l−, where K1 is the axial vector
meson, are calculated in the universal extra dimension (UED) model. The dependence of …
