On a possibility to extract a signal from heavy gluino cascade decays via isolated muon detection at the LHC energies
800 GeV gluino pair production is simulated using ISASUSY 1.1 MC-program. The cascade decay of the gluino into two lightest neutralinos, $\widetilde{g} \rightarrow \widetilde{\chi}_2^0 X$, $\widetilde{\chi}_2^0 \rightarrow \mu^+ \mu^- \widetilde{\chi}_1^0$, is studied for a convenient set of SUSY pa...

description | 800 GeV gluino pair production is simulated using ISASUSY 1.1 MC-program. The cascade decay of the gluino into two lightest neutralinos, $\widetilde{g} \rightarrow \widetilde{\chi}_2^0 X$, $\widetilde{\chi}_2^0 \rightarrow \mu^+ \mu^- \widetilde{\chi}_1^0$, is studied for a convenient set of SUSY parameters: $\mu$ = 200 GeV, tan$\beta$ = 2, average squark masses of 1600 GeV, charged Higgs mass of 500 GeV, and top quark mass of 140 GeV. With such parameters the mass difference between $\widetilde{\chi}_2^0$ and $\widetilde{\chi}_1^0$ is less than the mass of Z. As a background, $t\bar{t}$, Z + jets, WW, WZ and ZZ events were generated using ISAJET 6.50 MC-program. The granularities and energy resolutions of the calorimeters in the pseudorapidity range of $\mid\eta\mid$ < 5 are taken into account. If missing transverse momentum is greater than 200 GeV, the number of jets in the calorimeters is 4 or more, the invariant mass of two isolated muons is less than 80 GeV, the background in the muon transverse momentum distribution is negligible. |
