The Collins effect connects transverse quark spin with a measurable azimuthal dependence in the yield of hadronic fragments around the quark's momentum vector. Using two different reconstruction methods we observe statistically significant azimuthal asymmetries for charged pion pairs in e+e- annihilation at a center-of-mass energy of 10.52 GeV, which can be attributed to a transverse polarization of the primordial quarks. The measurement was performed using a sample of 79 million hadronic events collected with the Belle detector.

Hyperon-pair spin tomography beyond scalar spin correlations
Scalar Lambda-pair spin correlations leave a continuous density-matrix degeneracy; full tensor tomography is required to claim entanglement, and a ³P₀ benchmark predicts a specific anisotropy pattern.
