A Study of Stops Decaying Into Final States with Large Jet Multiplicities for $\sqrt{s}$ = 13 TeV

After almost a decade, no supersymmetric particles and SUSY signals have been detected so far. The proponents then aimed to analyze a SUSY signal, the pair production of the top squark, decaying into a chargino, $\tilde{\chi}^{\pm}_1$, and a bottom quark against the most prominent background which i...

Sumario:After almost a decade, no supersymmetric particles and SUSY signals have been detected so far. The proponents then aimed to analyze a SUSY signal, the pair production of the top squark, decaying into a chargino, $\tilde{\chi}^{\pm}_1$, and a bottom quark against the most prominent background which is the multijet. The proponents generated the background and signal events using PYTHIA 8.301. The proponents first observed the jet multiplicities of the background and signal events, and found out that they peaked at different values. We then wrote a custom Rivet analysis to analyze the different distributions of the signal and background events. The jet and $b$-jet multiplicity plots of the signal and background events show that these two are different. We also introduced jet multiplicity cuts to distinguish the signal from the background, which was later on found out to be effective. Lastly, the proponents attempted to reconstruct the $\tilde{\chi}^{\pm}_1$ mass, $m_{\tilde{\chi}^{\pm}_1}=$ 750 GeV, but unfortunately failed to do so.
