摘要：We calculate form factors relevant for rare B decays using moving-NRQCD for the b quark and the
AsqTad action for the light quarks. Moving NRQCD allows us to work directly with the physical
b quark mass and go to higher recoil momentum compared to standard NRQCD. Here, we show
first results for the matrix elements and the operator matching coefficients. Some difficulties and
possible ways of improvement are discussed.
