Operator Products in the SU() Principal Chiral Model
Peter Orland
The SU() principal chiral model is asymptotically free and integrable in dimensions. In the large- limit, there is no scattering, but correlation functions are {\em not…
A unitary renormalizable model of composite gravitons
Peter Orland
A four-dimensional confining Yang-Mills field, coupled to a fundamental fermion field and a bi-fundamental scalar field, has excitations with spin-2, but no other qua…
The universal coefficient of the exact correlator of a large- matrix field theory
Eytan Katzav, Peter Orland
Exact expressions have been proposed for correlation functions of the large- (planar) limit of the -dimensional principal chiral sigma mod…
Seeing asymptotic freedom in an exact correlator of a large- matrix field theory
Peter Orland
Exact expressions for correlation functions are known for the large- (planar) limit of the -dimensional principal chiral sigma model. Thes…
Dynamical Mass Reduction in the Massive Yang-Mills Spectrum in 1+1 dimensions
Axel Cortes Cubero, Peter Orland
The (1+1)-dimensional SU}(N) Yang-Mills Lagrangian, with bare mass M, and gauge coupling e, naively describes gluons of mass M. In fact, renormalization forces M to infinity. The s…
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…
