Abstract：
In this paper we calculate the contributions to the branching ratio of B_s→γγ from charged pseudo-Goldstone bosons appearing in the one generation Technicolor model. We find that the theoretical value of the branching ratio, BR(B_s→γγ), 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 B_s→γγ can test new physical signals from the technicolor model.
