Findings

Determined the phase boundary location in two-flavor QCD.

Validated the use of imaginary chemical potential with analytic continuation.

Provided insights into the QCD phase transition at finite density.

Abstract

We report our recent results on the QCD phase diagram obtained from the lattice QCD simulation. The location of the phase boundary between hadronic and QGP phases in the two-flavor QCD phase diagram is investigated. The imaginary chemical potential approach is employed, which is based on Monte Carlo simulations of the QCD with imaginary chemical potential and analytic continuation to the real chemical potential region.
