Technipion contribution to $b\to s\gamma$

Abstract

We show that the present limit on the inclusive decay $b\to s\gamma$ provides strong constraints on Technicolor models. In particular, small values of $F_{\pi }$ and the mass of charged octet and singlet technipions are excluded, assuming the most natural form of the technipion coupling to the ordinary quarks.
