New Physics effects on decay $B_s\to \gamma \gamma$ in Technicolor Model

Abstract

In this paper we calculate the contributions to the branching ratio of $B_s\to \gamma \gamma$ from the charged Pseudo-Goldstone bosons appeared in one generation Technicolor model. We find that the theoretical values of the branching ratio, $BR(B_s\to \gamma \gamma )$, including the contributions of PGBs, $P^{\pm }$ and $P_8^{\pm }$, are much different from the $SM$ prediction. The new physics effects can be enhance 2-3 levels to $SM$ result. It is shown that the decay $B_s\to \gamma \gamma$ can give the test the new physics signals from the technicolor model.
