摘要：

We apply a hard-scattering model based on quantum-chromodynamic perturbation theory to the production of hadrons at large transverse momentum by transversely polarized beam and target protons. We find that, at large xT=2pTs, the spin-spin asymmetry ANN for the case of transversely polarized protons is significantly smaller than the corresponding asymmetry ALL for longitudinally polarized protons. This situation is due to the relatively smaller size of both the quark-quark scattering asymmetry and the spin-dependent distribution functions for quarks in the transversely polarized proton. © 1979 The American Physical Society.
