Measuring the chargino parametersJ KALINOWSKI Instytut Fizyki Teoretycznej UW, Hoza 69, 00681 Warszawa, Poland Abstract. After the supersymmetric particles have been discovered, the priority will be to determine independently the fundamental parameters to reveal the structure of the underlying supersymmetric theory. In my talk I discuss how the chargino sector can be reconstructed completely by measuring the cross-sections with polarized beams at e+e- collider experiments: e+e-®[(c)\tilde]i+ [(c)\tilde]j- [i,j = 1,2]. The closure of the two-chargino system can be investigated by analysing sum rules for the production cross-sections. Keywords. Supersymmetry; chargino. Pacs No. 12.60; 14.80.-j; 14.80.Ly; 11.30.Pb |
