Exclusive radiative and electroweak b → d and b → s penguin decays at NLO

We provide standard model expectations for the rare radiative decays B -> K*gamma B -> rho gamma and B -> omega gamma, and the electroweak penguin decays B -> K*l(+)l(-) and B -> rho l(+)l(-) at the next-to-leading order (NLO), extending our previous results to b -> d transitions. We consider branching fractions, isospin asymmetries and direct CP asymmetries. For the electroweak penguin decays, the lepton-invariant mass spectrum and forward-backward asymmetry is also included. Radiative and electroweak penguin transitions in b. d are mainly interesting in the search for new flavor-changing neutral current interactions, but in addition the B -> rho gamma decays provide constraints on the CKM parameters (<(rho)over bar >, <(eta)over bar >). The potential impact of these constraints is discussed.
