The nonlocal Lagrangian, constrained by requirements of local gauge invariance and Lorentz-invariant ultraviolet regularization, generates additional interactions associated with gauge links. We use these to compute the full set of proton $\\to$ meson + baryon splitting functions, which in general contain on-shell and off-shell contributions, in addition to $\\delta$-function t","authors_text":"A.
