英文摘要: In this paper we calculate the contributions to the branching ratio of B-->X(s) gamma from the charged pseudo Goldstone bosons appearing in the one generation technicolor model. The current CLEO experimental results can eliminate a large part of the parameter space in the m(P-+/-)-m(P-8(+/-)) plane, and specifically, one can put a strong lower bound on the masses of color octet charged PGB's P-8(+/-):m(P-8(+/-))>400 GeV at 90% C.L. for free m(P-+/-).
