Description
By imposing flavor-dependent boundary conditions on quarks,
we construct three-flavour SU(3) gauge theory reconciling fundamental
fermion representation and exact Z3 center symmetry.
In this talk, we show the first result of lattice simulation on this QCD-like theory,
which we call Z3-QCD, with emphasis on the finite-temperature phase
transition with respect to center and chiral symmetries. On the lattice,
we formulate Z3-symmetric SU(3) gauge theory with three fundamental
Wilson quarks by twisting quark boundary conditions in a compact dimension.
We calculate the finite-temperature vacuum expectation value of Polyakov
loop and the chiral condensate. We find out the first-order center phase transition
where the hysteresis of temperature dependence exists depending on cold and hot starts. We also discuss the chiral crossover transition, and its relation to the center phase transition.
