摘要：

The inclusive process b-->sgamma is studied in the littlest Higgs model. The contributions arising from new particles are normally suppressed by a factor of O(v(2)/f(2)). Because of the large uncertainties of experimental measurements and theoretical predictions, the model parameters can escape from the constraints of present experiments provided fgreater than or equal to1 TeV.
