Mass shell is a synonym for mass hyperboloid, meaning the hyperboloid in energy–momentum space describing the solutions to the equation: $${\displaystyle E^{2}- {\vec {p}}\, ^{2}c^{2}=m_{0}^{2}c^{4}}$$, the mass–energy equivalence formula which gives the energy $${\displaystyle E}$$ in terms of the … Ver mais In physics, particularly in quantum field theory, configurations of a physical system that satisfy classical equations of motion are called "on the mass shell" or simply more often on shell; while those that do not are called "off … Ver mais An example comes from considering a scalar field in D-dimensional Minkowski space. Consider a Lagrangian density given by $${\displaystyle {\mathcal {L}}(\phi ,\partial _{\mu }\phi )}$$. … Ver mais WebThere is the so-called dispersion relation that relates mass, energy, and momentum: [math]E^2– (pc)^2= (mc^2)^2 [/math], or choosing “natural” units such that [math]c=1 [/math] (which is what particle physicists often do), [math]E^2-p^2=m^2 [/math]. Real particles, which are observed, obey this relationship.

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".
