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 π+, π0, and K±, as well as in the difference of the π+ and π- cross sections. © 2009 The American Physical Society.
