| 英文摘要 | The O(alpha(s)) corrections to the inclusive decay of b --> X(c)tau<(nu)over bar> and b --> X(s)gamma are calculated in technicolor with scalars model, and the latest experimental results from ALEPH and CLEO are used in determining the (sigma, h) parameter space. We find that in contrast with the enhancement of the branching ratio of b --> X(c)tau<(nu)over bar> relative to that of the standard model is very small, the b --> X(s)gamma decay width normalized by the standard model result can be reduced by as much as -50% when the ALEPH experimental value is used. In particular, the CLEO measurement which corresponds to the -33% reduction gives a more stringent constraint than B-(B) over bar mixing. The branching fraction B(b --> X(s)gamma) computed in the model in part of its parameter space with sizable deviation from the standard model prediction can be observable in the forthcoming few years with the upgraded CLEO detector and B-factories at SLAC and KEK.
