Resolving the B-> phi K* Polarization Anomaly

Hou, Wei-Shu · Nagashima, Makiko

Original · EN

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.
