Abstract (data abstract)
CERN-LHC. The results of a search for top and bottom squarks from gluino pair production produced in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample used is the full 2011 data set with an integrated luminosity of 4.7 fb-1. A previous paper (PR D85(2012)112006 - arXiv:1203.6193) presented similar results using the data set from the first half of 2011. The search is performed in events with large missing transverse momentum and at least 3 jets identified as originating from a b-quark. Exclusion limits are presented for a variety of gluino-mediated models.
