Rare decays of B-mesons

Technical Report:

Abstract

This paper is organized as follows. First, we discuss the decay rates for b {yields} (s,d) + {gamma} in the lowest order (1 loop) and including the QCD corrections in the effective Hamiltonian method. The photon energy spectrum in the inclusive decays B {yields} X{sub s} + {gamma} is evaluated in this approach and the dominant background from the CC decays B {yields} X{sub c} + {gamma} is presented. Next, we discuss the calculations for the inclusive decays b {yields} s + anti l (l = e,{mu},{nu}), including the QCD corrections. Finally, we summarize rate estimates for the exclusive rare decays of the B-meson, B {yields} K*{gamma}, and B {yields} (K,K*) anti l (l = e,{mu},{nu}), as well as B{sup o}{sub s,d} {yields} {gamma}{gamma} and B{sup o}{sub s,d} {yields} l{sup +}l{sup -} with (l = e,{mu},r). (orig./HSI).
