Searches for squark- and gluino-production in hadronic final states with the ATLAS detector

Weak-scale supersymmetry is one of the best motivated and studied extensions of the Standard Model. The recent increase in the centre-of-mass energy of the proton--proton collisions at the Large Hadron Collider gives a unique opportunity to extend the sensitivity to production of supersymmetric particles. ATLAS results on searches for supersymmetric squarks and gluinos, including third generation squarks produced directly or via decay of gluinos are presented. The searches involved final states containing jets (possibly identified as coming from $b$-quarks), missing transverse momentum and no leptons. They were performed on $3.2~\mathrm{fb}^{-1}$ proton--proton data collected in 2015. The limits obtained in the searches extend significantly beyond the ones obtained in Run 1 of the LHC.
