(physics) Pertaining to hadrodynamics.

(physics) The study of the laws that govern the motion and interaction of hadrons

(quantum mechanics) A framework for describing the nuclear many-body problem as a relativistic system of baryons and mesons based on a local, Lorentz-invariant lagrangian density.

(physics) The study of classical relativistic equations of motion for actions involving extended nucleons interacting with massive, neutral scalar and vector meson fields.
