Linked from

The 14 pages that link to Four-momentum, each with the reason it gives.

• Compton scatteringRelated: Conservation of four-momentum yields the photon’s wavelength shift.

• Lorentz transformationRelated: Lorentz transformations mix energy and momentum between observers just as they mix time and space.

• Feynman diagramRelated: Momentum labels on diagram lines express conservation at each vertex.

• Mass–energy equivalenceRelated: Its invariant magnitude links a system's energy and momentum to its mass.

• Stress–energy tensorRelated: The tensor extends four-momentum from a particle to a local distribution and flow.

• Spacetime intervalRelated: Its invariant norm gives the particle’s mass, paralleling the interval’s invariant norm of displacement.

• Invariant massRelated: Its Minkowski norm is invariant and determines the system’s invariant mass.

• Muon decayRelated: Its conservation among three products creates the continuous electron-energy range.

• Virtual particleRelated: Internal four-momentum need not obey the mass-shell condition.

• Poincaré groupRelated: Spacetime translations generate conservation of four-momentum.

• Massless particleRelated: A massless particle has a lightlike four-momentum with zero squared norm.
