WebThe observations indicate a strong violation of the helicity selection rule in χc2 decays into vector and pseudoscalar meson pairs. The measured branching fractions of χc2→K∗(892)K̄ are more than ten times larger than the upper limit of χc2→ρ(770)±π, which is so far the first direct observation of a significant U-spin symmetry breaking effect in charmonium decays.

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. jayda in stitches mitered granny square
