Abstract
We study the decays of B s,d →l + l - γ(l=e,μ,τ) within the light-front model. We calculate the tensor type form factors and use these form factors to evaluate the decay branching ratios. We find that, in the standard model, the branching ratios of B s(d) →l + l - γ (1=e,μ,τ) are 7.1×10 -9 (1.5×10 -10 ), 8.3×10 -9 (1.8 ×10 -10 ), 1.6×10 -8 (6.2×10 -10 ), respectively.
