1/mQ Corrections to the Heavy-to-Light-Vector Transitions in the HQET
Abstract
Within the HQET, the heavy to light vector meson transitions are systematically analyzed to the order of 1/mQ. Besides the four universal functions at the leading order, there are twenty-two independent universal form factors at the order of 1/mQ. Both the semileptonic decay B-> which is relevant to the |Vub| extraction, and the penguin induced decay B -> K* which is important to new physics discovering, depend on these form factors. Phenomenological implications are discussed.
