N2 - We construct non-Abelian global string solutions in the U (N)L × U (N)R linear sigma model. These strings are the most fundamental objects which are expected to form during the chiral phase transitions, because the Abelian η′ string is marginally decomposed into N of them. We point out Nambu-Goldstone modes of C PN - 1 for breaking of SU (N)V arise around a non-Abelian vortex.
