Characteristics of jets from the decay of stopped exotic particles in the ATLAS detector

The supersymmetry theory predicts the existence of sparticles that decay some later time after they were produced. To better understand the properties of these, the study of jet substructure variables within jets created during simulated long-lived gluino decays was conducted. Three Monte-Carlo simulated decays for different gluino and neutralino masses and one cosmic run (taken during 2016) were used in the analysis . To obtain the signals from gluinos it is necessary to take into account many backgrounds and carefully separate those. The distributions of jet variables such as energy, transverse momentum, jet’s location within the ATLAS detector define the features of any signal and allow to choose selection criteria. Those variables and correlation between them were studied in this work.
