Search for supersymmetry at the LHC

Supersymmetry is one of the best motivated extensions to the standard model that provides a solution to the hierarchy problem. The discovery of supersymmetry at the weak scale is straightforward at the LHC and the parameters of the underlying model can be determined. Extensive studies have been performed for minimal supergravity, gauge mediated and R-parity violating models. We review these studies in this paper.
