Abstract:
The O(αs) correction to the inclusive decay of b→X sγ 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 mixing. The model predictions can be observable in the forthcoming few years with upgraded CLEO detector and B-factories.
