Abstract

The sensitivity of four top-quark production process to a subset of dimension-8 SMEFT operators involving third-generation fermions is investigated. Bounds on the corresponding Wilson coefficients are derived using the recent experimental observation of the process. Matching between the dimension-8 SMEFT and the stabilized Randall–Sundrum (RS1) model is performed, and the relevant SMEFT constraints are translated into limits on RS1 model parameters. While the obtained bounds are weaker than existing constraints from other processes, primarily due to theoretical uncertainties, the results highlight the potential of four top-quark production as a complementary probe of extradimensional models.
