Abstract

The experimental observation of sizable transverse components for B-> phi K* decay is in strong contrast to all other VV modes, and poses a challenge to our understanding of B decay dynamics. Observing that the gluon emitted from b-> sg(*) chromodipole transition is transverse, we give a heuristic model where the transverse phi descends from the emitted gluon, hence similar phenomena should occur for B-> omega K* but not for B-> rho0 K*. New physics in bsg chromodipole coupling, perhaps needed for the B -> phi KS CP violation anomaly, may lead to different patterns of CP and T violation in transverse components of B -> phi K*, omega K* decays.
