摘要：The formulation of NRQCD discretized in a reference frame boosted relative to the B rest frame
will enable calculation of B form factors over a larger range of momentum transfer. We have
initiated a program to calculate form factors describing the rare decay B→K∗g . We discuss the
strategy and challenges of the project. As a first step in the numerical calculations, we present
first results for bottomonium quantities using the O(L2
QCD/m2,v4
NR) moving NRQCD action.
