Abstract
A search for squarks and gluinos is one of the primary targets among the supersymmetry particles at the Large Hadron Collider experiments because their cross sections are relatively large. Multi-bin and multivariate techniques are newly introduced in the searches for squarks and gluinos in final states with jets and missing transverse momentum in an event. This analysis uses data corrected in 2015-2018 with the ATLAS detector at $\sqrt{s}=13$ TeV, corresponding to the integrated luminosity of 139 fb$^{-1}$.
No significant excess over the Standard Model predictions is observed and the exclusion limits for the squark and gluino pair production in simplified models are set. In case of massless neutralino, squark (gluino) masses are excluded up to 1940 (2350) GeV at the 95 % confidence level.
