Abstract

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.
