Description
In this paper we calculate the contributions to the branching ratio of Bs →γ γ from charged pseudo-Goldstone bosons appearing in the one generation Technicolor model. We find that the theoretical value of the branching ratio, BR(Bs → γ γ), including the contributions of PGBs, P± and P±8 , is very different from the standard model (SM) prediction. The new physical effects can provide a one to two order of magnitude enhancement of the SM results. It is shown that the decay Bs → γ γ can test new physical signals from the technicolor model.
