Search for direct third-generation squark pair production in final states with missing transverse momentum and two b-jets in √s = 8 TeV pp collisions with the ATLAS detector

The results of a search for pair production of supersymmetric partners of the Standard Model third-generation quarks are reported. This search uses 20.1 fb −1 of pp collisions at √s = 8TeV collected by the ATLAS experiment at the Large Hadron Collider. The lightest bottom and top squarks (b 1 and t...

description The results of a search for pair production of supersymmetric partners of the Standard Model third-generation quarks are reported.

The lightest bottom and top squarks (b 1 and t 1 respectively) are searched for in a final state with large missing transverse momentum and two jets identified as originating from b-quarks. No excess of events above the expected level of Standard Model background is found. The results are used to set upper limits on the visible cross section for processes beyond the Standard Model.
