Abstract

We investigate the chiral transition of U(3) lattice gauge theory based on the strong coupling expansion. A generalized vertex model with vertices and weights derived from the tensor network approach of the dual representation of lattice QCD with staggered fermions is used and the configurations are sampled by the Metropolis algorithm. We study the chiral transition in the chiral limit and focus on the dependence of the second-order chiral transition temperature aT_c for different values of the lattice gauge coupling β. We compare different orders of truncations of the strong coupling expansion: Ord(β⁰), Ord(β¹), and Ord(β²). We comment on the prospects of extending to SU(3) at finite density.
