Using dihadron fragmentation functions as spin analyzers, the paper shows that Bell inequality violation in massless quark pairs can be probed through azimuthal correlations, with projected discovery significance from Belle data.

abstract
The spin correlation of back-to-back dihadron emerges in unpolarized high-energy collision, empowering unpolarized experiments to shed light on the spin-dependent fragmentation functions. This work investigates the transverse spin correlation of back-to-back dihadron in unpolarized $e^+e^-$, $pp$, and $\gamma p$ collisions, which serves as a novel probe of the chiral-odd fragmentation function $H_{1T}(z)$. We compute the transverse spin correlation at the partonic level and establish a connection with helicity amplitudes. Measuring this observable in future experiments can reveal valuable information on the hadronization of transversely polarized quarks.

Bell Inequality Violation of Light Quarks in Back-to-Back Dihadron Pair Production at Lepton Colliders
Using dihadron fragmentation functions as spin analyzers, the paper shows that Bell inequality violation in massless quark pairs can be probed through azimuthal correlations, with projected discovery significance from Belle data.
