    "abstract": "We develop a method for constructing the Heavy Baryon Chiral Perturbation\nTheory Lagrangian (L_{HBChPT}), to a given chiral order, within HBChPT. We work\nwithin SU(2) theory, with only the pion field interacting with the nucleon. The\nmain difficulties, which are solved, are to develop techniques for implementing\ncharge conjugation invariance, and for taking the nucleon on shell, both within\nthe nonrelativistic formalism. We obtain complete lists of independent terms in\nL_{HBChPT} through O(q^3) for off- shell nucleons. Then, eliminating\nequation-of-motion (eom) terms at the relativistic and nonrelativistic level\n(both within HBChPT), we obtain L_{HBCHPT} for on-shell nucleons, through\nO(q^3). The extension of the method (to obtain on-shell L_{HBChPT} within\nHBChPT) to higher orders is also discussed.",
