Abstract (data abstract)
CERN-LHC. A search for SUSY particles in 7 TeV proton-proton collisions in events with large missing transverse momentum and at least one heavy flavour jet. The data, with a total integrated luminosity of 35 pb-1, are analysed in the zero-lepton plus 3 jets and one-lepton plus 2 jet channels with at least one of the jets being a heavy flavour candidate. Jets are defined with the anti-Kt algorithm with R=0.4. In the zero-lepton data the effective mass (M(C=EFFECTIVE)) is defined as the scalar sum of the missing transverse energy and the transverse momenta of the highest PT jets. In the one-lepton data the transverse mas (MT) is constructed from the highest PT lepton and the missing ET.
