Testing the Feasibility of Tri-Higgs Production at LHC

While the groundbreaking discovery of the Higgs Boson in 2012 at the Large Hadron Collider (LHC) filled in the last piece of the puzzle for the Standard Model. Though the study continues, the full set of Higgs boson production modes at the LHC and the associated mechanisms are yet to be measured. Di-Higgs and tri-Higgs production especially allow us to inspect the parameters of Higgs self-coupling and the shape of the Higgs potential. Such processes are rare, so, we use Monte Carlo simulation to generate particle collision events to study kinematic features of di- Higgs and tri-Higgs production. An event here contains all the information recorded for one collision. These properties allow us to infer the production rate of di-Higgs and tri-Higgs at LHC, which allows us to constrain the Higgs coupling parameters, giving us the shape of the Higgs potential. We have measured the production rate of three boosted Higgs and two boosted Higgs. We are currently looking into the kinematic properties of these Higgs production modes and will further constrain the Higgs self-coupling parameters in the future.
