SEARCH FOR CHARGINO/NEUTRALINO PAIRS IN PP-COLLISIONS IN THE SU(2)(L)XSU(2)(R)XU(1)(B-L) 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 with Higgs triplets is considered. We study in detail production of chargino and neutralino pairs at the LHC pp-collider of centre of mass energy root s = 16 TeV. A numerical analysis for different sets of mass values of charginos and neutralinos is considered. The analysis shows that the signatures are an increase of the total cross sections sigma(T)(pp --> <(chi)over tilde>(+)(1)<(chi)over tilde>(-)(1), <(chi)over tilde>(1)(0)<(chi)over tilde>(0)(1) + X) > sigma(T)(pp --> <(chi)over tilde>(+)(2)<(chi)over tilde>(1)(-), <(chi)over tilde>(0)(2)<(chi)over tilde>(0)(1) + X) > sigma(T)(pp --> <(chi)over tilde>(2)(+)<(chi)over tilde>(-)(2), <(chi)over tilde>(0)(2)<(chi)over tilde>(0)(2) + X) in the region of the transverse momentum, k(t). The analysis also shows that the experimental signatures depend essentially on the mixing matrix parameters of the L-R SUSY model.
