The projection of spin along momentum; Lorentz invariant for massless particles but frame-dependent for massive particles.

This is an authored directed relation from the source endpoint to the target endpoint.
Helicity is the projection of spin along momentum.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-physics-helicitypdg-rppwp-physics-spinnlab-physics-spinEach relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
The experiment determined the emitted neutrino’s helicity to be negative within its assumptions.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
