Study of dynamical supersymmetry breaking for the two dimensional lattice Wess-Zumino model
M. Beccaria, G. F. De Angelis, M. Campostrini +1
A new approach to the study of the transition point in a class of two dimensional Wess-Zumino models is presented. The method is based on the calculation of rigorous lower bounds o…
Predictions and recent results in susy on the lattice
Alessandra Feo
In this brief review, I summarize the current theoretical knowledge in supersymmetry on the lattice, with special emphasis on recent results in the framework of N=1 supersymmetric…
Exact supersymmetry on the lattice: the Wess-Zumino model
Marisa Bonini, Alessandra Feo
It is shown that the lattice Wess-Zumino model written in terms of Ginsparg-Wilson fermions is invariant under a generalized supersymmetry transformation which is determined by an…
Phase diagram of the lattice Wess-Zumino model from rigorous lower bounds on the energy
Matteo Beccaria, Massimo Campostrini, Gian Fabrizio De Angelis +1
We study the lattice N=1 Wess-Zumino model in two dimensions and we construct a sequence of exact lower bounds on its ground state energy density , converging to i…
Supersymmetry breaking in two dimensions: the lattice N=1 Wess-Zumino model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We study dynamical supersymmetry breaking by non perturbative lattice techniques in a class of two-dimensional N=1 Wess-Zumino models. We work in the Hamiltonian formalism and anal…
Wess-Zumino model with exact supersymmetry on the lattice
Marisa Bonini, Alessandra Feo
A lattice formulation of the four dimensional Wess-Zumino model that uses Ginsparg-Wilson fermions and keeps exact supersymmetry is presented. The supersymmetry transformation that…
