Matrix formulation of superspace on 1D lattice with two supercharges
Sergio Arianos, Alessandro D'Adda, Alessandra Feo +2
Following the approach developed by some of the authors in recent papers and using a matrix representation for the superfields, we formulate an exact supersymmetric theory with two…
Lattice supersymmetry in 1D with two supercharges
S. Arianos, A. D'Adda, N. Kawamoto +1
A consistent formulation of a fully supersymmetric theory on the lattice has been a long standing challenge. In recent years there has been a renewed interest on this problem with…
Exact Extended Supersymmetry on a Lattice: Twisted N=4 Super Yang-Mills in Three Dimensions
Alessandro D'Adda, Issaku Kanamori, Noboru Kawamoto +1
We propose a lattice formulation of three dimensional super Yang-Mills model with a twisted N=4 supersymmetry. The extended supersymmetry algebra of all the eight supercharges is f…
Exact Extended Supersymmetry on a Lattice: Twisted N=2 Super Yang-Mills in Two Dimensions
Alessandro D'Adda, Issaku Kanamori, Noboru Kawamoto +1
We propose a lattice action for two dimensional super Yang-Mills theory with a twisted N=2 supersymmetry. The extended supersymmetry is fully and exactly realized on the lattice. T…
Twisted N=2 exact SUSY on the lattice for BF and Wess-Zumino
Alessandro D'Adda, Issaku Kanamori, Noboru Kawamoto +1
We formulate exact supersymmetric models on a lattice. We introduce noncommutativity to ensure the Leibniz rule. With the help of superspace formalism, we give supertransformations…
