Abstract
As described in Chapter four, supersymmetry is a well motivated extension to the standard model. According to this theory, each particle in the standard model has a supersymmetric partner whose spin differs from the standard model particle by one-half unit. The naturalness principle suggests that the masses of the superparticles should be of the order of 1 TeV [1–3]; therefore, the superparticles should be within our reach at high energy colliders like the LHC at CERN. One of the supersymmetry signals with a relatively high cross section is the production of a pair of gluinos that decay to four or more hadronic jets in the final state. In this search, in addition to the above mentioned assumptions, we also assume that R-parity is conserved with the consequence that the lightest SUSY particle is stable [4] and perhaps weakly interacting. Therefore, it leaves our detectors undetected, resulting in a huge amount of missing energy. As a result, one possible signal that we can search for is characterized by significant missing energy and a large number of jets.

The activity variable is defined as the sum p T of PF candidates in an annulus outside the isolation cone up to ΔR = 0.4 relative to the p T of the lepton. This variable is designed as a measure of hadronic activities around each lepton.
