The Ginsparg-Wilson(G-W) relation for chiral symmetry is extended for a supersymmetrical(SUSY) case on a lattice. It is possible to define exact lattice supersymmetry which are devided into two different cases according to using difference operators. U(1)R symmetry on the lattice is also realized as one of exact symmetries. For an application, the extended G-W relation is given for a two-dimens...

Lattice QCD allows us to simulate QCD at non-zero temperature and/or densities. Such equilibrium thermodynamics calculations are relevant to the physics of relativistic heavy-ion collisions. I give a brief review of the field with emphasis on our work.

A method is proposed for latticizing a class of supersymmetric gauge theories, including N=4 super Yang-Mills theory. The technique is inspired by recent work on “deconstruction”. Part of the target theory’s supersymmetry is realized exactly on the lattice, reducing or eliminating the need for fine tuning. (Talk based on the paper Supersymmetry on a Spatial Lattice, hep-lat/0206019, by D.B.K., ...

We calculate the electromagnetic form factor of the pion in quenched lattice QCD. The non-perturbatively improved Sheikoleslami-Wohlert lattice action is used together with the consistently O(a) improved current. We calculate the pion form factor for masses down to mπ = 360 M eV , extract the charge radius, and extrapolate toward the physical pion mass. In the second part, we discuss results fo...
