The Compact Muon Solenoid (CMS) detester is part of Large Hadron Collider (LHC) at CERN, last run in 2012 with a center of mass energy 8 TeV proton-proton collision. A study of the Z-boson production at LHC gives tests of the standard model in a new energy field also might show exotic physics processes. Before the LHC some of the Z boson decay into two muons are known from the LEP experiments and these characteristic are used for calibration as well as alignment of the LHC experiments. This thesis describes the efficiency and cross-section σ measurement for the processes pp [arrow right] γ/Z [arrow right] μ + μ - at the CMS experiment of the 2012 with integrated luminosity of 20 pb -1 . These measurement have been done using one of the Monte Carlo generator which is pythia8. In the process of the production of the Z boson and its decay there are jets production, to study these jets a method of reconstruction are used. The anti - k T algorithm is used to reconstruct the jets.
