One of the powerful tools to study strongly coupled field theories is duality - the claim that certain strongly coupled field theories are equivalent to (generally different) weakly coupled theories. I will discuss aspects of non-abelian Chern-Simons theory coupled to non-supersymmetric fundamental matter in three-spacetime dimensions, focusing on a dual pair known as quasi-fermionic theories: the critical boson and the regular fermion. I will address an apparent puzzle in the Higgsed phase of the critical boson theory - regarding the characteristics of the Z-boson and its dual fermionic interpretation. By employing 3d Bose-Fermi duality, I will derive the exact large N result for the two-point function of the Z-boson and explore its spectral representation, highlighting the implications.
