Ward Identities for N = 2 Rigid and Local Supersymmetry in Euclidean Space
نویسنده
چکیده
We construct and check by explicit Feynman diagram calculations the BRST Ward identities for N = 2 rigid super Yang-Mills theory and N = 2 extended supergravity in four-dimensional Euclidean space without auxiliary fields. We use the Batalin-Vilkovisky formalism. In the supergravity case we need one new contractible pair of complex spinor fields to obtain the usual gauge-fixing term and corresponding Nielsen-Kallosh ghosts.

Superconformal Ward Identities and N = 2 Yang-mills Theory
A reformulation of the superconformal Ward identities that combines all the supercon-formal currents and the associated parameters in one multiplet is given for theories with rigid N = 1 or N = 2 supersymmetry. This form of the Ward Identities is applied to spontaneously broken N = 2 Yang-Mills theory and used to derive a condition on the low energy effective action. This condition is satisfied...
متن کاملA Two-Dimensional Lattice Model with Exact Supersymmetry
Starting from a simple discrete model which exhibits a supersymmetric invariance we construct a local, interacting, two-dimensional Euclidean lattice theory which also admits an exact supersymmetry. This model is shown to correspond to the Wess-Zumino model with extended N = 2 supersymmetry in the continuum. We have performed dynamical fermion simulations to check the spectrum and supersymmetri...

متن کاملComments on N = ( 2 , 2 ) supersymmetry on two - manifolds
We study curved-space rigid supersymmetry for two-dimensional N = (2, 2) supersymmetric fields theories with a vector-like R-symmetry by coupling such theories to background supergravity. The associated Killing spinors can be viewed as holomorphic sections of particular complex line bundles over Euclidean space-time, which severely restricts the allowed supersymmetric couplings on compact orien...
متن کاملA Lattice Study of the Two-Dimensional Wess Zumino Model
We present results from a numerical simulation of the two-dimensional Euclidean Wess-Zumino model. In the continuum the theory possesses N = 1 supersymmetry. The lattice model we employ was analyzed by Golterman and Petcher in [1] where a perturbative proof was given that the continuum supersymmetric Ward identities are recovered without finite tuning in the limit of vanishing lattice spacing. ...
