Supersymmetry (SUSY) is one of the most promising theories which could explain physics
beyond the Standard Model (SM). Under R-parity conservation, the Lightest SUSY Particle
(LSP) could be a candidate for the Dark Matter (DM). The Large Hadron Collider (LHC)
provides proton-proton collisions at the world���fs highest energies, where production of
coloured SUSY particles is highly expected. In this seminor, search for gluino
pair-production will be presented which use events with large missing ET, jets, and no
lepton in the final states of the proton-proton collisions recorded by the ATLAS
detector at sqrt(s)= 13 TeV in 2015.
