Nucleon decay matrix elements with the Wilson quark action: an update

Abstract: We present a new lattice computation of matrix elements of baryon number violating operators which appear in the low-energy effective Lagrangian of (SUSY-)Grand Unified Theories. A subtle point in the calculation, which has caused an inconsistency between the direct computation of the matrix elements through three-point functions and the indirect computation using the soft poin theorem, is discussed.
