Search for dark matter with a Leptoquark and Missing transverse energy in the final state by using proton-proton collision data of CMS detector at LHC at 13 TeV

Leptoquarks are new bosons predicted by numerous extensions of standard model(SM), having both lepton and baryon number. In the final state for this particular dark matter (DM) search, the selected events should have at least one high transverse momentum muon, one high transverse momentum jet and large missing transverse momentum (MET). A new paradigm coannihilation codex, where DM particle will either annihilate or produce in conjunction with a coannihilation partner X , is used for the this analysis. A pair of scalar leptoquarks are produced, where one decays to a high transverse momentum muon and a jet, and the other decays to dark matter and some undetected SM particles called X. The peak in the invariant mass distribution of the leptoquark, where it decays to highest transverse momentum muon and jet, will give the signature of dark matter. The results will be presented using Run2 proton-proton collision data of the CMS detector at LHC.
