A new physics scenario shows that four-fermion operators of Nambu-Jona-Lasinio (NJL) type have a strong-coupling UV fixed point, where composite fermionsF(bosons) form as bound states of three (two) SM elementary fermions and they couple to their constituents via effective contact interactions at the composite scale(TeV). We present a phenomenological study to investigate such composite particles at the LHC by computing the production cross sections and decay widths of composite fermions in the context of the relevant experiments at the LHC withppcollisions atTeV andTeV. Systematically examining all the different composite particlesFand the signatures with which they can manifest, we found a vast spectrum of composite particlesFthat has not yet been explored at the LHC. Recasting the recent CMS results of the resonant channel(as), we find that the composite fermion massbelow 4.25 TeV is excluded for/= 1. We further highlight the region of parameter space where this specific composite particleFcan appear using 3, expected by the High-Luminosity LHC, computing 3 and 5contour plots of its statistical significance.
