$B \to X_{s}\gamma$ in supersymmetry : large contributions beyond the leading order / Degrassi, G ; Gambino, Paolo ; Giudice, Gian Francesco
We discuss possible large contributions to B -> X_s gamma, which can occur at the next-to-leading order in supersymmetric models. They can originate from terms enhanced by tan(beta) factors, when the ratio between the two Higgs vacuum expectation values is large, or by logarithm of M_{susy}/M_W, when the supersymmetric particles are considerably heavier than the W boson.
