In the QCDF approach, at the rest frame of the heavy B meson, B meson can decay into two light mesons with large momenta.
In order to obtain the CP violation of [bar.B] [right arrow] [[rho].sup.0]([omega])[[rho].sup.0]([omega]) [right arrow] [[pi].sup.+][[pi].sup.-] ([[pi].sup.+])([[pi].sup.-]) in (16), we calculate the amplitudes [t.sub.[rho]], [t.sup.a.sub.[rho]], [t.sub.[omega]], [t.sup.a.sub.[omega]], [p.sub.[rho]], [p.sup.a.sub.[rho]], [p.sub.[omega]], and [p.sup.a.sub.[omega]] in (18) and (19) in the QCDF approach, which are tree-level and penguin-level amplitudes.
Power corrections in QCDF always involve endpoint divergences which produce some uncertainties.
