Query: Nucleon Decay Matrix Elements for Domain-Wall Fermions   We report on the nucleon decay matrix elements with domain-wall fermions in
quenched approximation. Results from direct and indirect method are compared
with a focus on the process of a proton decaying to a pion and a lepton. We
discuss the renormalization necessary for the matching to the continuum theory.
Preliminary results for the renormalized chiral lagrangian parameters are
presented.
