Abstract We discuss the role of the axial U(1)A symmetry in the chiral phase transition using the U(Nf)R×U(Nf)L linear sigma model with two massless quark flavours. We expect that above a certain temperature, the axial U(1)A symmetry will be effectively restored as well as SU(Nf)R×SU(Nf)L. Then we can construct a string-like static solution of the η string and a kink-like classical solution of the domain wall during the chiral phase transition. We give out the possible signals for detecting the domain wall in ultrarelativistic heavy-ion collisions.
