Abstract

The interference fragmentation function translates the fragmentation of a quark with a transverse projection of the spin into an azimuthal asymmetry of two final-state hadrons. In e ⁺e ^- annihilation the product of two interference fragmentation functions is measured. We report nonzero asymmetries for pairs of charge-ordered π ⁺π ^- pairs, which indicate a significant interference fragmentation function in this channel. The results are obtained from a 672fb ^-1 data sample that contains 711×106 π ⁺π ^- pairs and was collected at and near the Υ(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e ⁺e ^- collider.
