Abstract

This thesis presents an in-depth, non-perturbative investigation of symplectic gauge theories, focusing on the Sp(4) gauge group coupled to fermions in both the fundamental and two-index antisymmetric representations. These models are particularly relevant to Beyond the Standard Model (BSM)physics,...
