Photonic and Leptonic Rare B Decays

Abstract

Some selected topics involving photonic and leptonic rare B decays are reviewed. The interest in their measurement for the CKM phenomenology is underlined. They are also potentially interesting in searching for physics beyond the standard model. This is illustrated on the examples of the decays $B \to (K,K^*) \ell^+ \ell^-$ and $B \to (\rho, \omega) \gamma$ by contrasting their anticipated phenomenological profiles in the standard model and some variants of supersymmetric models.Comment: 24 pages, 5 figures (requires epsf); Invited Talk, Beauty 2000, Sea of Galilee, Israel, September 13 - 19, 200
