Abstract
Abstract We present a complete and extensive analysis of associated chargino and neutralino production in the framework of a supersymmetric theory augmented by left-right symmetry. This model provides additional gaugino and higgsino states in both the neutral and charged sectors, thus potentially enhancing new physics signals at the LHC. For a choice of benchmark scenarios, we calculate cross sections for 7, 8 and 14 TeV. We then simulate events expected to be produced at the LHC, and classify them according to the number of leptons in the final state. We devise methods to reduce the background and compare the signals with consistently simulated events for the Minimal Supersymmetric Standard Model. We pinpoint promising scenarios where left-right symmetric supersymmetric signals can be distinguished both from background and from the Minimal Supersymmetric Standard Model events.

We present a complete and extensive analysis of associated chargino and neutralino production in the framework of a supersymmetric theory augmented by left-right symmetry
Most of the superpartners likely to be produced at the LHC will not be detected as such, as they will eventually decay into the lightest supersymmetric particle (LSP), which is stable as long as the R-parity is conserved
Summary
The so-called left-right supersymmetric models are based on the SU(3)c × SU(2)L × SU(2)R × U(1)B−L gauge group. We provide the masses and mixing matrices for the chargino and neutralino sectors, relevant for this work, and leave additional details and our conventions for the appendix
