Abstract (data abstract)
CERN-LHC. Search for pair production of the lighter scalar partners of top quarks (STOP1) in proton-proton collisions at a centre-of-mass energy of 7 TeV using data with a total integrated luminosity of 2.05fb-1. Events with two same flavour opposite-sign leptons (E or MU) with invariant mass consistent with a Z-boson (86-96 GeV), having large missing transverse momentum and jets, one being identified as a b-quark jet) in the final state are considered. Data is presented here from plots in the paper and from the auxilliary material linked below.
