Spontaneous Breaking of N=2 to N=1 in Rigid and Local Supersymmetric Theories
S. Ferrara, L. Girardello, M. Porrati
We analyze the relation between rigid and local supersymmetric N=2 field theories, when half of the supersymmetries are spontaneously broken. In particular, we show that the recent…
On the N = 2 supersymmetric CP(N) sigma model and Chern Simons terms
Massimiliano Ciuchini, J. A. Gracey
We use the large self consistency method to compute the critical exponents of the fields and coupling of the supersymmetric CP(N) sigma model at leading order in in vario…
Critical Behavior of Simplicial Chiral Models
R. C. Brower, M. Campostrini, K. Orginos +3
The large-N saddle-point equations for the principal chiral models defined on a d-1 dimensional simplex are derived from the external field problem for unitary integrals. The saddl…
Monte Carlo study of exact S-matrix duality in non simply laced affine Toda theories
Matteo Beccaria
The \ pair of non simply laced affine Toda theories is studied from the point of view of non perturbative duality. The classical spectrum of each member is…
Faddeev-Popov determinant in 2-dimensional Regge gravity.
Pietro Menotti, Pier Paolo Peirano
By regularizing the singularities appearing in the two dimensional Regge calculus by means of a segment of a sphere or pseudo-sphere and then taking the regulator to zero, we obtai…
The QED(0+1) model and a possible dynamical solution of the strong CP problem
J. Loeffelholz, G. Morchio, F. Strocchi
The QED(0+1) model describing a quantum mechanical particle on a circle with minimal electromagnetic interaction and with a potential -M cos(phi - theta_M), which mimics the massiv…
