Supersymmetry on a Euclidean Spacetime Lattice I: A Target Theory with Four Supercharges
نویسندگان
چکیده
We formulate a Euclidean spacetime lattice whose continuum limit is (2, 2) supersymmetric Yang-Mills theory in two dimensions, a theory which possesses four supercharges and an anomalous global chiral symmetry. The lattice action respects one exact supersymmetry, which allows the target theory to emerge in the continuum limit without fine-tuning. Our method exploits an orbifold construction described previously for spatial lattices in Minkowski space, and can be generalized to more complicated theories with additional supersymmetry and more spacetime dimensions.

Supersymmetry on a Euclidean Spacetime Lattice II: Target Theories with Eight Supercharges
We formulate Euclidean spacetime lattices whose continuum limits are supersymmetric Yang-Mills theories with eight supercharges in two and three dimensions. The lattice actions are themselves supersymmetric.
متن کاملSupersymmetric quiver gauge theories on the lattice
In this paper we detail the lattice constructions of several classes of supersymmetric quiver gauge theories in two and three Euclidean spacetime dimensions possessing exact supersymmetry at finite lattice spacing. Such constructions are obtained through the methods of topological twisting and geometric discretization of Euclidean Yang-Mills theories with eight and sixteen supercharges in two a...
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 کاملLattice supersymmetry, superfields and renormalization
We study Euclidean lattice formulations of non-gauge supersymmetric models with up to four supercharges in various dimensions. We formulate the conditions under which the interacting lattice theory can exactly preserve one or more nilpotent anticommuting supersymmetries. We introduce a superfield formalism, which allows the enumeration of all possible lattice supersymmetry invariants. We use it...
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...
