B --> K$*\gamma$ decay on APE

We present results for the radiative decay B\rightarrow K^* \gamma, obtained by using the Clover action at \beta = 6.0 on APE. The compatibility between the scaling laws predicted by the Heavy Quark Effective Theory (HQET) and pole dominance is discussed. The final result depends crucially on the as...

Sumario:We present results for the radiative decay B\rightarrow K^* \gamma, obtained by using the Clover action at \beta = 6.0 on APE. The compatibility between the scaling laws predicted by the Heavy Quark Effective Theory (HQET) and pole dominance is discussed. The final result depends crucially on the assumed q^2-dependence of the form factors.
