One loop calculation of SUSY Ward-Takahashi identity on lattice with Wilson fermion
نویسنده
چکیده
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 SUSY Ward-Takahashi identity coincide with that from the axial U(1)R symmetry as was suggested by Curci and Veneziano. Two important symmetries of the super Yang-Mills theory can be recovered simultaneously in the continuum with a single fine tuning. Typeset using REVTEX

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 کاملNucleon axial charge from quenched lattice QCD with domain wall fermions and DBW2 gauge action
The domain wall fermion (DWF) method, with its almost perfectly preserved chiral symmetry on the lattice, makes the calculation of the nucleon axial charge particularly easy. By maintaining chiral symmetry and using the Ward-Takahashi (WT) identity, one has ZA = ZV and the bare lattice calculation yields the physical value without explicit renormalization. The DBW2 improved gauge action provide...
متن کاملOne loop renormalization for the axial Ward - Takahashi identity in Domain - wall QCD
We calculate one-loop correction to the axial Ward-Takahashi identity given by Furman and Shamir in domain-wall QCD. It is shown perturbatively that the renormalized axial Ward-Takahashi identity is satisfied without fine tuning and the “conserved” axial current receives no renormalization, giving ZA = 1. This fact will simplify the calculation of the pion decay constant in numerical simulation...
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 کاملChecking the transverse Ward-Takahashi relation at one loop order in 4-dimensions
Some time ago Takahashi derived so called transverse relations relating Green’s functions of different orders to complement the well-knownWard-Green-Takahashi identities of gauge theories by considering wedge rather than inner products. These transverse relations have the potential to determine the full fermion-boson vertex in terms of the renormalization functions of the fermion propagator. Fo...
