We find that those regions that closely follow Joy's law do not show any twist-tilt dependence.

Summing our two-loop express WebThis property is related to the concept of parity and to the conservation laws which apply to particle interactions. For neutrinos the spin is always opposite the linear momentum and this is referred to as "left-handed", whereas the antineutrinos are always "right-handed". This evokes the picture of the right-hand rule for vector angular momentum.
