Observation of the naive-T-odd Sivers effect in deep-inelastic scattering.
Azimuthal single-spin asymmetries of leptoproduced pions and charged kaons were measured on a transversely polarized hydrogen target. Evidence for a naive-T-odd, transverse-momentum-dependent partonExpand

Measurement of the deuteron spin structure function g1d(x) for 1 (GeV/c)2 < Q2 < 40 (GeV/c)2
Abstract New measurements are reported on the deuteron spin structure function g1d. These results were obtained from deep inelastic scattering of 48.3 GeV electrons on polarized deuterons in theExpand

Measurement of the tensor structure function b1 of the deuteron.
The Hermes experiment has investigated the tensor spin structure of the deuteron using the 27.6 GeV/c positron beam of DESY HERA. The use of a tensor-polarized deuteron gas target with only aExpand

Transverse target single-spin asymmetry in inclusive electroproduction of charged pions and kaons
Single-spin asymmetries were investigated in inclusive electroproduction of charged pions and kaons from transversely polarized protons at the HERMES experiment. The asymmetries were studied as aExpand

Correlated strength in the nuclear spectral function.
We have carried out an (e,e'p) experiment at high momentum transfer and in parallel kinematics to measure the strength of the nuclear spectral function S(k,E) at high nucleon momenta k and largeExpand

Measurement of the virtual-photon asymmetry A2 and the spin-structure function g2 of the proton
A measurement of the virtual-photon asymmetry A2(x,Q2) and of the spin-structure function g2(x,Q2) of the proton are presented for the kinematic range 0.004<x<0.9 and 0.18 GeV2<Q2<20 GeV2. The dataExpand
