In this dissertation, you will find a study of di-boson production in pp collision with the Compact Muon Solenoid (CMS) detector at Large Hadron Collider (LHC).A study of Z process is performed on the data collected by the CMS during 2011 and corresponding to integrated luminosity L= 5 fb -1 .The study consists of two parts: cross section measurement and setting the limits on anomalous trilinear gauge couplings (aTGC) between a Z boson and a photon.The measured cross-section of Z agrees within the uncertainties with the standard model predicted cross section at next to leading order.Having found no excess in cross section measurement, we set the 95% confidence level (C.L.) limit on aTGC, corresponding to:011 and |h Z 4 | < 0.00011.Another study discussed is a study of a low-scale walking Technicolor model with T and a T production in the fully leptonic final state at 95% C.L. in proton-proton collisions at s = 10 TeV scenario using Monte Carlo simulation.We conclude that such processes can be excluded with 366 pb -1 of data for T masses up to 400 GeV and the observation would require 2.8 fb -1 of data with 5 precision.
