We present a model calculation of leading order interference fragmentation functions arising from the distribution of two hadrons produced in the same jet of a fragmenting quark in a hard process. Using a simple spectator model for the mechanism of the hadronization process, for the first time we give a complete calculation and numerical estimates for the example of a proton-pion pair production with its invariant mass on the Roper resonance.

  1. Single spin asymmetry $A _ { U L } ^ { \sin ( 3 \phi _ { h } - \phi_{ R } ) }$ in dihadron production in SIDIS

    hep-ph 2025-09 conditional novelty 6.0 of 10

    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.

  2. Dihadron azimuthal asymmetry and light-quark dipole moments at the Electron-Ion Collider

    hep-ph 2024-08 unverdicted novelty 6.0 of 10

    Proposal for a new observable—dihadron azimuthal asymmetry in unpolarized SIDIS at EIC—that isolates linear dependence on light-quark dipole couplings via SM-dipole interference.
