Abstract:
We study the phenomenological implications of the Suu diquark scalar production at the LHC. We introduce a hypothetical ultraheavy particle emerging from the direct collision of two up quarks. Suu is decaying into two vectorlike quarks, which are subsequently decaying only into Standard Model particles. Starting from the theoretical model that is built using the FeynRules package in Mathematica, then generating the Monte Carlo samples in MadGraph5 and implementing the appropriate machine learning techniques to discriminate the signal from the background, we analyze the feasibility of searching for ultraheavy scalars at the 13-13.6 TeV LHC.
