Abstract: There is current interest in searching for beyond the standard model particles produced in association with a top quark pair, tt + X(X→ t t). This project focuses on a top-philic Z* resonance model that may significantly enhance the tttt cross section. The all-hadronic channel is explored in the resolved regime using a novel machine learning algorithm, SPA-Net, which performs permutation-invariant jet-parton assignment to reconstruct events. This talk presents initial limits using this network to discriminate signal against large QCD multijet- and tt-dominated backgrounds. Studies shown use Monte Carlo simulations of proton-proton collision data gathered by the CMS detector at the LHC.
