Radiative Penguin and Leptonic Rare Decays at BABAR
Recent BABAR results on rare B decays involving flavour-changing neutral currents or purely leptonic final states are presented. New measurements of the CP asymmetries in B {yields} K*{gamma}, B {yields} K*{sub 2}(1430){gamma}, and b {yields} s{gamma} are reported, as well as a new measurement of the B {yields} K*{gamma} branching fraction. Also reported are updated limits on B {yields} {mu}{nu} and recent measurements of B {yields} K(*){ell}{ell} and b {yields} s{ell}{ell}. The data sample comprises 123 {center_dot} 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring.
