Inelastic electron-nucleon scattering is governed by relativistic quantum mechanics and Special Relativity, where cross-section modifications account for particle recoil, spin interactions (via magnetic dipole fields), and Lorentz boosts through the Rosenbluth formula. Theoretical analysis distinguishes elastic from inelastic processes based on invariant mass conservation ($W^2 = P_i \cdot P_f + Q^2$), identifying resonance formations as transient excited states of composite particles like protons that decay into secondary hadrons such as pions. This framework establishes the theoretical basis for probing internal substructure via form factors, transitioning classical point-particle models to those describing resonances and quark constituents within quantum field theory domains.
