Spectroscopy of SU(4) gauge theory with two flavors of sextet fermions

TL;DR

This paper explores the spectral properties of an SU(4) gauge theory with two sextet fermion flavors, providing initial computational results on mesons, diquarks, and baryons, and comparing findings with large-Nc theoretical expectations.

Contribution

It offers the first detailed spectroscopy analysis of SU(4) gauge theory with sextet fermions, including meson, diquark, and baryon mass calculations, and compares results with large-Nc predictions.

Findings

Computed meson and diquark masses

Measured pseudoscalar and vector decay constants

Determined six-quark baryon masses

Abstract

We present a first look at the spectroscopy of SU(4) gauge theory coupled to two flavors of Dirac fermions in the two-index antisymmetric representation, which is a real representation. We compute meson and diquark masses, the pseudoscalar and vector meson decay constants, and the masses of six-quark baryons. We make comparisons with large-Nc expectations.
