QCD Phase Transition and Hadron Bubble Formation in the Dual Ginzburg-Landau Theory

Abstract

We study the QCD phase transition at finite temperature and discuss the hadron bubble formation in the dual Ginzburg-Landau theory, which is an effective theory of QCD and describes the color confinement via QCD-monopole condensation. We formulate the effective potential at various temperatures and find that thermal effects reduce the QCD-monopole condensate and bring a first-order deconfinement phase transition. Based on this effective potential at finite temperature, we investigate properties of hadron bubbles created in the early Universe and discuss the hadron bubble formation process.
