Supersymmetric discovery potential and benchmarks for early runs at √s=7 TeV at the LHC

We carry out an analysis of the potential of the Large Hadron Collider (LHC) to discover supersymmetry in runs at root s = 7 TeV with an accumulated luminosity of (0.1-2) fb(-1) of data. The analysis is done with both minimal supergravity and supergravity models with nonuniversal soft breaking. Benchmarks for early discovery with (0.1-2) fb(-1) of data are given. We provide an update of b-tagging efficiencies in PGS 4 appropriate for LHC analyses. A large number of signature channels are analyzed, and it is shown that each of the models exhibited are discoverable at the 5 sigma level or more above the standard model background in several signature channels which would provide cross checks for a discovery of supersymmetry. It is shown that some of the benchmarks are discoverable with 0.1 fb(-1) of data again with detectable signals in several channels.
