Polarisation in sfermion decays : determining tanb and trilinear couplings.

Boos, E. and Martyn, H.-U. and Moortgat-Pick, G. and Sachwitz, M. and Sherstnev, A. and Zerwas, P. M. (2003) 'Polarisation in sfermion decays : determining tanb and trilinear couplings.', European physical journal C., 30 (3). pp. 395-407.


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 and or decays to leptons and t quarks plus neutralinos or charginos can be used to measure (in particular for large values) and to determine the trilinear couplings , At and Ab in sfermion pair production.
