Systematic parametrization of the leading B-meson light-cone distribution amplitude
Abstract We propose a parametrization of the leading B-meson light-cone distribution amplitude (LCDA) in heavy-quark effective theory (HQET).In position space, it uses a conformal transformation that yields a systematic Taylor expansion and an integral bound, which Crank Axle Bearing enables control of the truncation error.Our parametrization furth
