The exclusive decay B --> $\varrho$e$\nu$ beyond model calculations

Due to its comparatively theoretical ``simplicity'', the decay channel B\to\rho e \nu offers one of the best possibilities to determine the CKM matrix element |V_{ub}| accurately. I present a new calculation of the relevant hadronic form factors from light-cone sum rules. I also review the...

description Due to its comparatively theoretical ``simplicity'', the decay channel B\to\rho e \nu offers one of the best possibilities to determine the CKM matrix element |V_{ub}| 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.
