Abstract
We investigate the radiative dileptonic decays Bs → l+l−γ (l = e, μ and τ) in the framework of the topcolor-assisted technicolor (TC2) model. The contributions of the new particles predicted by this model to the branching ratios and the forward-backward asymmetry (AFB) of these decays are considered. It is found that the values of their branching ratios are greater than the standard model (SM) predictions by several times up to one order of magnitude and |AFB| can also be enhanced by several times in a wide range of the parameter space.
