Abstract

We measured the spin asymmetry in the scattering of 100 GeV longitudinally-polarized muons on transversely polarized protons. The asymmetry was found to be compatible with zero in the kinematic range 0.006 < x < 0.6, 1 < Q² < 30 GeV². From this result we derive the upper limits for the virtual photon-proton asymmetry A₂, and for the spin structure function g₂. For x < 0.15, A₂ is significantly smaller than its positivity limit √R.

Funding Information: The nucleon spin-dependent structure functions, gl and g2, can be determined in deep inelastic scattering of polarized charged leptons on polarized nucleons. Both are important for the understanding of nucleon spin structure. The structure function gl is used to test QCD sum rules, and in the quark-parton model it determines the contribution of the quark spins to the 15 Supported by the National Science Foundation. 16 Supported by Ishida Foundation, Mitsubishi Foundation and Monbusho International Science Research Program. 17 Supported by the National Science Foundation (NWO) of the Netherlands.

N2 - We measured the spin asymmetry in the scattering of 100 GeV longitudinally-polarized muons on transversely polarized protons. The asymmetry was found to be compatible with zero in the kinematic range 0.006 < x < 0.6, 1 < Q2 < 30 GeV2. From this result we derive the upper limits for the virtual photon-proton asymmetry A2, and for the spin structure function g2. For x < 0.15, A2 is significantly smaller than its positivity limit √R.
