CHARGINO-NEUTRALINO PRODUCTION IN P(P)OVER-BAR-COLLISIONS FOR THE LEFT-RIGHT SUPERSYMMETRIC MODEL

An extension of the Supersymmetric Standard Model to the supersymmetric SU(2)L x SU(2)R x U(1)B-L model is considered. The gauge group contains a bi-doublet and triplet Higgs field. We investigate the possibility of detecting chargino and neutralino production in ppBAR-collisions at CDF, namely ppBAR --> W(L,R)BAR R + X --> chi(j)- chi(i)0 + X. A numerical analysis is performed for M(chi-) greater-than-or-equal-to 45 GeV, tan beta greater-than-or-equal-to 1 and a lower bound on the lightest supersymmetric particle (LSP) mass, chi greater-than-or-equal-to 14 GeV. Using conservative assumptions Of M(WR) greater-than-or-equal-to 300 GeV and g congruent-to g(L) congruent-to g(R), we find the cross sections are: sigma(L)(ppBAR --> W(L)- + X --> chi(j)- chi(i)0 + X) almost-equal-to 0.11 nb, and sigma(R)(ppBAR --> W(R)- + X --> chi(j)- chi(i)0 + X) almost-equal-to 4.6 pb, and thus sigma(L) greater-than-or-equal-to 24 sigma(R) at square-root s = 1.8 TeV. Cross sections are also given for larger values of the center of mass energy square-root s up to those available at the SSC. The results are compared with the prompt-lepton background of the W(L,R)BAR decays from ppBAR --> W(L,R)- + X --> l-nu(lL,R) + X. Both decays for W(L,R-) bosons show Jacobian peaks for p(T) = (1/2) square-root s congruent-to (1/2) M(WL) congruent-to 40 GeV (p(T) greater-than-or-equal-to 150 GeV for M(WR)) at theta = 90-degrees. Furthermore the chargino signature unlike the prompt-lepton background is symmetric under the Jacobian peak. We also exhibit the dependence of the angular distribution of the chargino on the c.m. angle theta for PT congruent-to 40 GeV, 150 GeV at square-root s = 1.8 TeV.
