摘　　要：在多标度人工色模型下计算了荷电PG玻色子对B介子稀有衰变B→Xs,dνν和Bs,d→l+ l-的贡献 ,抽出了描写新物理贡献的Co(xi)函数。计算表明 :K .In this paper,we calculate the contributions to the rare B-decays,B→X s,d ν ν (nu) and B s,d →l +l - from the unit charged technipions in the framework of the Multiscale Walking Technicolor Model.We separate the new funaction C New 0,which summarize the effects of the new physics beyond the SM.Within the parameter space,we find that the assumed masses of m p1 and m p8 in the multiscale walking Technicolor Model are excluded by the rare B-decay data.
