Search for pair production of gluinos in final states with many b-jetsand ETmiss at √s=13 TeV with the ATLAS detector

This poster presents a search for gluino pair production, in which both gluinos decay through virtual third generation squarks, stop or sbottom, into a final state with many b-jets, missing transverse momentum (ETmiss, coming from the lightest neutralino) and, in the case of stop-mediated decays, potentially also isolated leptons. The full dataset collected in 2015 by the ATLAS experiment in pp collisions at a center-of-mass energy of 13 TeV is used, amounting to a total integrated luminosity of 3.2 fb-1. No excess over the Standard Model prediction is found, and limits are set on simplified models, extending significantly those obtained in Run 1.
