Abstract: | We construct non-Abelian global string solutions in the UL(N)×UR(N) 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 CPN−1 for breaking of SUV(N) arise around a non-Abelian vortex. |
