Restoration of supersymmetry on the lattice: Two-dimensional N = (2, 2) supersymmetric Yang-Mills theory
نویسندگان
چکیده
By numerically investigating the conservation law of the supercurrent, we confirm the restoration of supersymmetry in Sugino’s lattice formulation of the twodimensional N = (2, 2) supersymmetric SU(2) Yang-Mills theory with a scalar mass term. Subtlety in the case without the scalar mass term, that appears to ruin perturbative power counting, is also pointed out.

O ct 2 00 8 Numerical simulation of N = 1 supersymmetric Yang - Mills theory
We present results from a lattice study of SU(2) color, N = 1 supersymmetric Yang-Mills theory using domain wall fermions. Supersymmetry in this particular lattice formulation is expected to emerge in the continuum and chiral limits without any fine-tuning of operators. Preliminary results for the static quark potential, residual mass, chiral condensate and spectrum–a potential indicator of sup...

We illustrate some physical application of a lattice formulation of the two-dimensional N = (2, 2) supersymmetric SU(2) Yang-Mills theory with a (small) supersymmetry breaking scalar mass. Two aspects, power-like behavior of certain correlation functions (which implies the absence of the mass gap) and the static potential V (R) between probe charges in the fundamental representation, are consid...
متن کاملA Euclidean Lattice Construction of Supersymmetric Yang-Mills Theories with Sixteen Supercharges
We formulate supersymmetric Euclidean spacetime Ad lattices whose classical continuum limits are U(N) supersymmetric Yang-Mills theories with sixteen supercharges in d = 1, 2, 3 and 4 dimensions. This family includes the especially interesting N = 4 supersymmetry in four dimensions, as well as a Euclidean path integral formulation of Matrix Theory on a one dimensional lattice.
متن کاملFrom Twisted Supersymmetry to Orbifold Lattices
We show how to derive the supersymmetric orbifold lattices of Cohen et al. [1, 2] and Kaplan et al. [3] by direct discretization of an appropriate twisted supersymmetric Yang-Mills theory. We examine in detail the four supercharge two dimensional theory and the theory with sixteen supercharges in four dimensions. The continuum limit of the latter theory is the well known Marcus twist of N = 4 Y...
