ResumoWe evaluate the decays $\stackrel{\ensuremath{\rightarrow}}{B}{K}^{*}\ensuremath{\pi},K(\ensuremath{\rho},\ensuremath{\omega},\ensuremath{\varphi})$ adding the long distance charming penguin contributions to the short distance: tree+penguin amplitudes. We estimate the imaginary part of the charming penguin contribution by an effective field theory inspired by heavy quark effective theory and parametrize its real part. The final results for branching ratios depend on only two real parameters and show a significant role of the charming penguin contributions. The overall agreement with the available experimental data is satisfactory.
