We report on the first extraction of interference fragmentation functions from the semi-inclusive production of two hadron pairs in back-to-back jets in e+e- annihilation. A nonzero asymmetry in the correlation of azimuthal orientations of opposite \pi+\pi- pairs is related to the transverse polarization of fragmenting quarks through a significant polarized dihadron fragmentation function. Extraction of the latter requires the knowledge of its unpolarized counterpart, the probability density for a quark to fragment in a \pi+\pi- pair. Since data for the unpolarized cross section are missing, we extract the unpolarized dihadron fragmentation function from a Monte Carlo simulation of the cross section.

    hep-ph 2025-12 conditional novelty 6.0 of 10

    A dihadron fragmentation azimuthal asymmetry at e+e− colliders can probe light-quark Yukawa couplings linearly and separate y_u from y_d at the 10^-4 level.

    A one-loop spectator-model calculation of the previously uncalculated T-odd dihadron fragmentation function predicts a near-zero sin(3phi_h-phi_R) asymmetry at COMPASS and HERMES, matching the weak observed signal.
