A lattice study of the exclusive B --> K$*\gamma$ decay amplitude, using the Clover action at $\beta$ = 6.0 / APE Collaboration
We present the results of a numerical calculation of the B\rightarrow K^* \gamma form factors. The results have been obtained by studying the relevant correlation functions at \beta=6.0, on an 18^3 \times 64 lattice, using the {\rm O(a)}-improved fermion action, in the quenched approximation. [...]

B --> K$*\gamma$ decay on APE / APE Collaboration
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. [...]

We present the results of a high statistics lattice calculation of hadronic form factors relevant for $D-$ and $B-$meson semi-leptonic decays into light pseudoscalar and vector mesons. The results have been obtained by averaging over 170 gauge field configurations, generated in the quenched approximation, at $\beta=6.0$, on a $18^3 \times 64$ lattice, using the $O(a)$-improved SW-Clover action.From the study of the matrix element $<K^-\vert J_\mu \vert D^0>$, we obtain $f_+ (0)=0.78\pm 0.08$ and from the matrix element $<\bar K^{* 0}\vert J_\mu \vert D^+>$ we obtain $V(0)=1.08\pm 0.22$, $A_1(0)=0.67\pm 0.11$ and $A_2(0)=0.49\pm 0.34$.
