Metastable nonconfining states in SU(3) lattice gauge theory with sextet fermions
Olga Machtey, Benjamin Svetitsky (Tel Aviv University)
TL;DR
This paper investigates the phase structure of SU(3) lattice gauge theory with sextet fermions, revealing metastable states with complex Wilson line phases near the finite-temperature transition, contrasting with the true equilibrium phase.
Contribution
It identifies and characterizes metastable nonconfining states with specific Wilson line phases in SU(3) lattice gauge theory with sextet fermions.
Findings
Metastable states have Wilson line phases near 2pi/3 or pi.
The true equilibrium phase has Wilson line aligned with the positive real axis.
Metastable states occur near the finite-temperature phase transition.
Abstract
We study the SU(3) lattice gauge theory, with two flavors of sextet Wilson-clover fermions, near its finite-temperature phase transition. We find metastable states that have Wilson line expectation values whose complex phases are near 2pi/3 or pi. The true equilibrium phase at these couplings and temperatures has its Wilson line oriented only towards the positive real axis, in agreement with perturbation theory.
