  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.
