The standard model (SM) of elementary particles successfully explains their interactions observed in nature. However, the SM is known to be an incomplete theory, e.g., it does not explain what the dark matter is made up of. After the discovery of Higgs boson of mass 125 GeV at the Large Hadron Collider (LHC) in 2012, the search for beyond standard model (BSM) physics is one of the prime motives of the current LHC physics program. Supersymmetry (SUSY) is the most popular BSM theory predicting a new partner for every SM particle differing by half spin, which can also provide a viable candidate for dark matter.
I will present a generic search for SUSY based on proton-on-proton collision events at
the LHC at centre-of-mass energy of 13 TeV, containing multiple jets and large missing
transverse momentum. We use a data sample corresponding to an integrated luminosity of 137 fb-1 collected by Compact Muon Solenoid (CMS) experiment during
2016-2018. The main feature of this classic search is a simultaneous coverage to
various SUSY topologies and kinematic phase spaces. The results will be presented in
the context of pair production of superparterns of quarks and gluons. I will also
comment on the advances under way which can potentially strengthen CMS-SUSY
program for upcoming Run 3 and high-luminosity operations of LHC.
