Abstract
We calculate, for the first time using unquenched lattice QCD form factors, the standard model differential branching fractions for , , and compare with experimental measurements by Belle, BABAR, CDF, and LHCb. We report on in bins used by experiment and predict . We also calculate the ratio of branching fractions and predict , for , . Finally, we calculate the “flat term” in the angular distribution of the differential decay rate in experimentally motivated bins.
