Observation of the Naive-T-Odd Sivers Effect in Deep-Inelastic Scattering

Airapetian, A. et al. (2009) Observation of the Naive-T-Odd Sivers Effect in Deep-Inelastic Scattering. Physical Review Letters, 103(15), p. 152002. (doi: 10.1103/PhysRevLett.103.152002)

Abstract

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 parton distribution function is deduced from nonvanishing Sivers effects for pi(+), pi(0), and K(+/-), as well as in the difference of the pi(+) and pi(-) cross sections.
