Description
The B --> V T (V and T denote vector and tensor mesons respectively) decays, whose final-state particles can have transverse or longitudinal polarization, are investigated in perturbative QCD (pQCD) approach. Measurements have been made of B --> phi K_2^*, and it is found that f_T / f_L is small, whereas f_T / f_L ~ 1 for B --> omega K_2^* where f_T(f_L) is the fraction of transverse (longitudinal) decays. It will be of great interest to measure f_L for these modes to test pQCD.
