bifurcation ratio

We find that: (a) the and can provide one to three orders enhancements to thebranching ratios of the rare K-decays under study; (b) the assumed mass ranges ofthe unit-charged PGBs in the Multiscale Walking Technicolor Model are excluded bythe rare K-decay data.

计算结果表明：（ａ）荷电ＰＧ玻色子可以对Ｋ介子稀有衰变分枝比给出１～３个量级的增强；（ｂ）根据现有实验数据，Ｋ。

Within the parameter space, we find that: (a) the P± and P8± can providerather large enhancements to the branching ratios of the rare B-decays in question, themaximum increase is about a factor of 3 to Br(B→Xs,d,vv), and a factor of 5 to Br (Bs,d→1+1-); (b) the color-octet pesudo-Goldstone boson P±8 dominates the contributions toall rare B-decays und.

计算表明：（ａ）荷电ＰＧ玻色子可以对Ｂ介子稀有衰变分枝比Ｂｒ（Ｂ→Ｘｓ，ｄＶＶ）和Ｂｒ（Ｂｓ，ｄ→１＋１－）给出３～５倍的增强；（ｂ）在大部分参数空间内，色八重态ＰＧ玻色子Ｐ８±起主要作用。
