Query: The heavy-to-light transitions in the light-cone QCD sum rules   We have analyzed the $B\to \pi $ and $B_{s}\to K$ semileptonic form factors
and $B\to V\gamma (V=K^*,\rho,\omega)$ processes in the light-cone QCD sum
rules. In order to enhance the predictivity and reliability of numerical
results the chiral-current correlator is employed and the twist-3 light-cone
wavefunction can be effectively eliminated from the sum rules.
