Double Spin Asymmetries for Large-$p_T$ Hadron Production in Semi-Inclusive DIS

Abstract

We study the twist-2 double-spin asymmetries for the 2-jets and large-$p_T$ hadron ($\pi$, $\Lambda$ etc) production in semi-inclusive deep inelastic scattering to $O({\alpha }_s)$ in perturbative QCD. After deriving the complete set of the polarized cross section which is differential with respect to the transverse momentum, we discuss characteristic features of the azymuthal spin asymmetries, using existing parton densities and fragmentation functions at COMPASS and EIC energies.
