摘要
The O(alpha(s)) correction to the inclusive decay of b-->X(s)gamma is calculated in the technicolor model with scalars. We find that the deviation of the decay width from the standard model prediction can be reduced by as much as 50% when ALEPH experimental value is used. In particular, the CLEO measurement which corresponds to the 33% reduction gives more stringent constraint on the parameter space in the technicolor with scalars model than B-(B) over bar mixing. The model predictions can be observable in the forthcoming few years with upgraded CLEO detector and B-factories.
