In this project I have studied the left-right symmetric model (LRSM) as a candidate beyond standard model theory of particle physics. The most common version of the theory, called the minimal LRSM, has been studied and tested extensively for several decades. I have therefore modied this minimal LRSM by adapting the scalar sector and computing the mass of the charged right-handed gauge bosons WR for this particular scalar sector. I carried out a study of the theory and implemented it into FeynRules, in order to simulate LHC events using MadGraph. This allowed computation of the cross-section for the decay WR to a top and a bottom quark as a function of the mass of WR , which was compared with CMS data for the same decay, with proton-proton collisions at a centre of mass energy of 13 TeV. The final result was a constraint on the mass of WR , with a lower bound of 3 TeV.
