Exact lattice Ward - Takahashi identity for the N = 1 Wess - Zumino model
We consider a lattice formulation of the four dimensional N = 1 Wess-Zumino model that uses the Ginsparg-Wilson relation. This formulation has an exact supersymmetry on the lattice. We show that the corresponding Ward-Takahashi identity is satisfied, both at fixed lattice spacing and in the continuum limit. The calculation is performed in lattice perturbation theory up to order g in the couplin...
متن کامل5 Exact Ward - Takahashi identity for the lattice N = 1 Wess - Zumino model
Abstract. The lattice Wess-Zumino model written in terms of the Ginsparg-Wilson relation is invariant under a generalized supersymmetry transformation which is determined by an iterative procedure in the coupling constant. By studying the associated Ward-Takahashi identity up to order g we show that this lattice supersymmetry automatically leads to restoration of continuum supersymmetry without...
متن کاملOne loop calculation of SUSY Ward-Takahashi identity on lattice with Wilson fermion
One loop correction to the SUSY Ward-Takahashi identity is calculated on lattice withWilson fermion. The supersymmetry on lattice is broken explicitly by the gluino mass and the lattice artifact. We should fine tune the theory to the point given by the additive mass correction to eliminate the breaking effect of lattice artifact. It is shown that the additive mass correction appearing from the ...
متن کاملA solution to Ward - Takahashi - identity in QED
Abstract We discuss the properties of fermion propagator in three dimensional QED with dressed photon based on spectral representation with LSZ reduction formula.We evaluate the spectral function by the sum of infinite numbers of rainbow type diagram for intermediate states.In this method we have the solution as one derived by renormalization group in four-dimension.Massless vacuum polarization...
متن کاملTransverse Ward - Takahashi Identity , Anomaly and Schwinger - Dyson Equation ∗
Based on the path integral formalism, we rederive and extend the transverse Ward-Takahashi identities (which were first derived by Yasushi Takahashi) for the vector and the axial vector currents and simultaneously discuss the possible anomaly for them. Subsequently, we propose a new scheme for writing down and solving the Schwinger-Dyson equation in which the the transverse Ward-Takahashi ident...
