Critical mass renormalization in renormalized phi4 theories in two and three dimensions
Andrea Pelissetto, Ettore Vicari
We consider the O(N)-symmetric phi4 theory in two and three dimensions and determine the nonperturbative mass renormalization needed to obtain the phi4 continuum theory. The requir…
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…
High-order perturbative expansions of multi-parameter Phi^4 quantum field theories
Andrea Pelissetto, Ettore Vicari
We present high-order pertubative expansions of multi-parameter Phi^4 quantum field theories with an N-component fundamental field, containing up to 4th-order polynomials of the fi…
The spectrum of SU(N) gauge theories at nonzero theta
Luigi Del Debbio, Gian Mario Manca, Haralambos Panagopoulos +2
We study the theta dependence of the spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the topological term in the Lagrangian, for N>=3 and in th…
Theta-dependence of the spectrum of SU(N) gauge theories
Luigi Del Debbio, Gian Mario Manca, Haralambos Panagopoulos +2
We study the theta dependence of the spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the topological term in the Lagrangian, for N>=3 and in th…
