Double spin asymmetry in dihadron production in SIDIS off the longitudinally polarized nucleon target
arXiv:1906.05674 · doi:10.1103/PhysRevD.100.094036
Abstract
In this paper we study the double longitudinal spin asymmetry of dihadron production in semi-inclusive deep inelastic scattering (SIDIS). We calculate a unknown twist-3 dihadron fragmentation function within a spectator model which has been used successfully in describing the dihadron production in both the unpolarized and the single polarized processes. The collinear picture, in which the transverse momentum of the final state hadron pair is integrated out, has been considered. The azimuthal asymmetry arises from the coupling and the coupling is studied. We estimate the asymmetry at the kinematics of COMPASS and compare with the data. The prediction at the future Electron Ion Collider (EIC) has also been presented.
