Abstract
All left-right models contain a second Z0, Z'. If the Z' is massive en ough it will decay into charginos chi(i)+/- and neutralinos chi(i)0. T he particular model being considered is an extension of the supersymme tric standard model (SSM) which has been modified to include both left and right symmetry groups: SU(2)L x x SU(2)R x U(1)B-L. In this paper the cross-sections have been calculated for the production of chargin os and neutralinos in the reaction e+e- --> Z' --> chi(i)+ chi(j)-, or chi(i)0chi(j)0, evaluating the Z'-reaction at the center-of-mass ener gy up to 2TeV for different sets of parameters. Choosing masses M(Z') = 400 GeV and M(chi2)0 = 63 GeV, M(chi2)+/- = 54 GeV, with g(R) congru ent-to g(L), GAMMA(Z') congruent-to 12 GeV, M(R) = 300 GeV, M(L) = 50 GeV and mu = = - 10 GeV the cross-sections were found to be sigma(e+e- --> Z' --> chi2+ chi2-) congruent-to 0.21 nb and sigma(e+e- --> Z' -- > chi2(0)chi2(0)) congruent-to 77 pb. Choosing masses M(Z') = 400 GeV and M(chi4)0 = = 171.7 GeV, M(chi2)+/- = 80 GeV, with g(R) congruent-t o g(L), GAMMA(Z') congruent-to 12 GeV, M(R) = 1000 GeV, M(L)4 = = 250 GeV and mu = - 80 GeV the cross-sections were found to be: sigma(e+e- --> Z' --> --> chi2+chi2-) congruent-to 0.11 nb and sigma(e+e- --> Z' --> chi2(0)chi2(0)) congruent-to 15 pb. Finally, choosing M(chi(i) not -equal-to M(chi(j)) masses of M(Z') = 400 GeV and M(chi1)0 = 158 GeV, M(chi2)0 = 171.7 GeV, M(chi2)+ = 80 GeV, M(chi1)- = 45.3 GeV, with g(R ) congruent-to g(L), GAMMA(Z') congruent-to 12 GeV, M(R) = 1000 GeV, M (L) = 250 GeV and mu = - 80 GeV the cross-sections were found to be: s igma(e+e- --> Z' --> chi2+chi1-) congruent-to congruent-to 0.32 nb and sigma(e+e- --> Z' --> chi2(0)chi1(0)) congruent-to 48 pb.
