The 12 pages that link to Invariant mass, each with the reason it gives.

• Mass–energy equivalenceRelated: It is the mass in the relation between a system's rest energy and its energy.

• Spacetime intervalRelated: It is another Lorentz invariant built from a spacetime metric, this time in energy-momentum space.

• Four-momentumRelated: A particle’s four-momentum magnitude determines its invariant mass in every inertial frame.

• Particle decayRelated: A parent particle's invariant mass sets the energy available to its decay products.

• Relativistic momentumCompared with: It remains fixed under Lorentz transformations, unlike momentum's frame-dependent components.

• Wigner classificationRelated: It distinguishes massive representation classes from massless ones.

• Electron massNarrower topic: The electron’s rest mass is its invariant mass.

• Energy–momentum relationRelated: The mass in the equation remains unchanged between inertial observers.

• Relativistic mechanicsRelated: It distinguishes intrinsic mass from quantities that vary with an observer's frame.

• Massless particleBroader topic: Zero invariant mass is the defining property of this particle class.

• Samuel C. C. TingRelated: A peak in the electron-pair invariant-mass spectrum revealed the J/ψ resonance.

• Landau–Yang theoremRelated: Diphoton invariant-mass peaks are used to identify candidate decaying resonances.
