✦ Synopsis

We report the current status of RBCK calculations on nucleon structure with both quenched and unquenched lattice &CD. The combination of domain wall fermions and DBW2 gauge action works well for quantities like isovector vector and axial charges, moments of structure functions (ST),, dl, and (l)ap, and nucleon decay matrix elements.

Good chiral symmetry is observed, and translates into continuum-like behavior of non-perturabtive renormalization where explicitly checked. Pion form factor calculation in the same framework is also reported.

I review the lattice formulations of vector-like gauge theories (e.g. QCD) with doma,in-wall/overlap fermions, and discuss how to optimize the chiral symmetry for any finite N, (sites in the fifth dimension). In this formulation, quark propagators in gauge background can be computed efficiently thr
