The Study of RS Graviton to HH at 13 TeV

We studied the simulated production of a Randall-Sundrum graviton decaying to Higgs bosons in proton-proton collisions at a center of mass of 13 TeV. Partons inside the protons interact to produce the RS graviton G*, which then undergoes the decay G* -> HH. The process was simulated using PYTHIA8 to generate events, with the FastJet 3 framework to find hadronic jets in the reaction products. Quantities such as the transverse momentum, pseudorapidity, azimuthal angle and the invariant mass of the first two jets from the simulation were compared through histograms made using ROOT. The cross section of the process was observed using different values of the coupling of the graviton. It was found out that the relation of these two quantities is parabolic. Also, ratios of N-subjettiness of the jets were calculated to distinguish the events where the jets come from the processes in Quantum Chromodynamics (QCD) from the events where the jets come Extra Dimensions (ED) processes.
