Characteristics of the Z boson in Chern-Simons matter theory

Year: 2025

Type: article

Abstract: We consider the Chern-Simons theory coupled to massive fundamental matter in three spacetime dimensions, focusing on the Higgsed phase of the bosonic matter in the large- N limit. To study the characteristics of the Z boson in the Higgsed phase and address an apparent puzzle regarding its fermionic analog, we employ the 3D Bose-Fermi duality to derive the exact large- N result for the two-point function of the Z boson. We study the spectral representation of the Z boson and find that, in the large- N limit, it behaves as an unstable resonance with a nonperturbatively large lifetime at weak coupling.
