PRODUCTION OF SCALAR ELECTRONS AND Z°-BOSON USING THE MSSM

Abstract

The main goals of this thesis are; a] Solving the parameter space of the minimal supersymmetric extension of the standard model (MSSM) up to s-lepton sector. b] Calcul ation of the interaction cross-section as a function of the center of mass energy (CME) for the process; e e Where j=: 1 is the ordering-number of physical s-leptons. The parameter space has been investigated at tree level in the frame of few physical assumptions as well as some proven arguments. The solution of the parameter-space is progressed according to a scheme that is suggested in this work. Mass spectrum of physical states SUSY partners as well as the transformation matrices are obtained up to slepton sector for two numerical instances, one instance at low value of Tan (3, and the other at high value of Tan (3. Specifically at Tan f3 =3, and Tan [3 -20. The interaction cross-section is calculated over several interaction channels for the The most probable channel is found to be that contains neutralinos j=l,2,3,4 and\or charged sleptons Lk ,k = The interaction cross section is found to it the center of mass energy about 395.87 GeV for Tan {3 =3.0, and 117.719 pbarn at the center of mass energy about 381.64 GeV for Tan (3 =20.0. The neutralino masses are restricted by the model itself to be in the range from 43.5 GeV up to 206.9 GeV.
