Hadronic weak decays in the heavy quark limit

We discuss exclusive charmless hadronic B decays. In particular we
perform a phenomenological analysis of the decay into 2
longitudinal vector mesons and present analytical
integral-expressions for the decay into proton and antiproton. The
light nucleon form factor is part of the decay amplitude into
protons and is calculated and regularized explicitly at subleading
power in the large energy limit.
