Abstract

It is shown that the chiral nonanalytic terms generated byΔ 33 resonance in the nucleon self-energy is reproduced in chiral perturbation theory by perturbing appropriate local operators contained in the pion-nucleon effective Lagrangian itself.

  11. The interaction Lagrangian for πNΔ could of course be written in a chiral invariant form, which when expanded in the pion field, would give (11) as the leading term. But we do not do so to emphasise the fact that Δ is considered here as a massive state not included explicitly as a basic field in our effective field theory
