WebWhen a particle is "on-shell", the "shell" being referred to is a particular surface in energy-momentum space. Specifically, it's the surface defined by: E^2-p^2=m^2 (in units where c=1), where m is the mass of the particle. So, if the energy and momentum of the particle are such that it satisfies this equation, then it's on that "shell".
