摘要We study the possible signals of the pion-string associated with the QCD chiral phase transition in LHC Pb-Ph collision at energy roots = 5.5 TeV. We follow the Kibble-Zurek mechanism to discuss the production and evolution of the pion string. We will show that if the QCD chiral phase transition really takes place in the LHC Pb-Pb collision process and the phase transition is in the second order, the pion string will be inevitably produced and subsequently decay. The main effect of this phenomenon is that there is a generation of a large number of pions in the final state produced by the decay of the pion string, and these pions are mostly distributed in a low momentum region with p similar to 143MeV; also there are lots of neutral pions distributed in a low momentum region with the mean momentum at p similar to 21 MeV.
