Multiparticle Form Factors of the Principal Chiral Model At Large N    [PDF]

Axel Cortés Cubero
We study the sigma model with $SU(N)\times SU(N)$ symmetry in 1+1 dimensions. The two- and four-particle form factors of the Noether current operators are found, by combining the integrable-bootstrap method with the large-$N$ expansion.
