Polarisation in Sfermion Decays: Determining \tanβand Trilinear Couplings
Preprint
- 13 March 2003
Abstract
The basic parameters of supersymmetric theories can be determined at future e^+e^- linear colliders with high precision. We investigate in this report how polarisation measurements in \tilde{\tau} and \tilde{t} or \tilde{b} decays to \tau leptons and t quarks plus neutralinos or charginos can be used to measure \tan\beta (in particular for large values) and to determine the trilinear couplings A_{\tau}, A_t and A_b in sfermion pair production.Keywords
