Like sign dilepton signature for gluino production at the CERN LHC with or without R conservation

The isolated like sign dilepton signature for gluino production is investigated at the CERN LHC energy for the R-conserving as well as the L- and B-violating SUSY models over a wide range of the parameter space. One gets viable signals for gluino masses of 300 and 600 GeV for both R-conserving and L-violating models, while it is less promising for the B-violating case. For a 1000 GeV gluino, the L-violating signal should still be viable; but the R-conserving signal becomes too small at least for the low luminosity option of the LHC
