31 Jan 2017 | | Abstract: | 800 GeV gluino pair production is simulated using ISASUSY 1.1 MC-program. The
cascade decay of the gluino into two lightest neutralinos, $widetilde{g}
ightarrow widetilde{chi}_2^0 X$, $widetilde{chi}_2^0
ightarrow mu^+
mu^- widetilde{chi}_1^0$, is studied for a convenient set of SUSY
parameters: $mu$ = 200 GeV, tan$eta$ = 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, $tar{t}$,
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 $midetamid$ < 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. | | Source: | arXiv, 1701.8889 | | Services: | Forum | Review | PDF | Favorites | |
