英文摘要: Rare decays B-s,B-d --> mu(+)mu(-) are evaluated in technicolor model with scalars. R-b is revisited to constrain the model parameter space. It is found that restriction on f/f' arising from Rb which was not considered in previous studies requires f/f' no larger than 1.9 at 95% confidence level, implying no significantly enhancement for Br(B-s,B-d --> mu(+)mu(-)) from neutral scalars in the model. However, the branching ratio of B-s --> mu(+)mu(-) can still be enhanced by a factor of 5 relative to the standard model prediction. With the value of f/f' less than or equal to 1.9, an upgraded Tevatron with an integrated luminosity 20 fb(-1) will be sensitive to enhancement of B-s --> mu(+)mu(-) in this model provided that neutral scalar mass m(sigma) is below 580 GeV (C) 2002 Elsevier Science B.V.
