So what exactly is the difference ... rbwh pharmacyWebTherefore, if a particle's spin vector points in the same direction as the momentum vector, the helicity is positive, and if they point in opposite directions, the helicity is negative. However, the helicity of a massless particle is always equal to its chirality. The helicity of a particle is a Lorentz invariant. Chirality, Neutrino, Spin sims 4 headline effects modA chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality.
