The Exclusive Decay B e Beyond Model Calculations
Abstract
Due to its comparatively theoretical ``simplicity'', the decay channel B e offers one of the best possibilities to determine the CKM matrix element |Vub| accurately. I present a new calculation of the relevant hadronic form factors from light-cone sum rules. I also review the results from lattice calculations and find that they agree with the results from light-cone sum rules where comparison is possible.\\ This paper relies on work done in collaboration with V.M.\ Braun.
