Non-diagonal flavour observables in B and Collider Physics

Abstract

Until now the focus within the direct search for supersymmetry has mainly been on flavour diagonal observables. Recently lepton flavour violating signals at future electron positron colliders have been studied. There is now an opportunity to analyse the relations between collider observables and low-energy observables in the hadronic sector. In a first work in this direction, we study flavour violation in the squark decays of the second and third generations taking into account results from B physics, in particular from the rare decay b ->s gamma. Correlations between various squark decay modes can be used to get more precise information on various flavour violating parameters.Comment: 3 pages, latex, Contribution to the International Europhysics Conference on High Energy Physics EPS03, 17-23 July 2003, Aachen, German
