Summary
By using the symmetry improved Cornwall-Jackiw-Tomboulis effective formalism, we study a pion string of the $O(4)$ linear sigma model at finite temperature in chiral limit. In terms of the Kibble-Zurek mechanism we reconsider the production and evolution of the pion string in a thermal bath created in LHC heavy ion collision experiment. Finally, we estimate the pion string density and its possible signal during the chiral phase transition.
