A large N phase transition in the continuum two dimensional SU(N) X SU(N) principal chiral model
R. Narayanan, H. Neuberger, E. Vicari
It is established by numerical means that the continuum large N principal chiral model in two dimensions has a phase transition in a smoothed two point function at a critical dista…

Theta dependence of SU(N) gauge theories in the presence of a topological term
Ettore Vicari, Haralambos Panagopoulos
We review results concerning the theta dependence of 4D SU(N) gauge theories and QCD, where theta is the coefficient of the CP-violating topological term in the Lagrangian. In part…
