The Integrable Bootstrap Program at Large N and its Applications in Gauge Theory
Axel Cortes Cubero
We present results for the large- limit of the (1+1)-dimensional principal chiral sigma model. This is an asymptotically-free matrix-valued field with massive excita…

Correlation Functions of the SU(infinity) Principal Chiral Model
Axel Cortes Cubero, Peter Orland
We obtain exact matrix elements of physical operators of the (1+1)-dimensional nonlinear sigma model of an SU(N)-valued bare field, in the 't Hooft limit N goes to infinity. Specif…
