Title: Azimuthal asymmetries in single polarized proton-proton Drell-Yan processes

Abstract

We study the azimuthal asymmetries in proton-proton Drell-Yan processes with one incident proton being transversely or longitudinally polarized. We consider particularly the asymmetries contributed by the leading-twist chiral-odd quark distributions. We analyze the asymmetries with sin(2{phi}+{phi}{sub S}) and sin(2{phi}-{phi}{sub S}) modulations in transverse single polarized p{sup {up_arrow}p} Drell-Yan and sin2{phi} asymmetries in longitudinal single polarized p{sup {yields}p} Drell-Yan at the Relativistic Heavy Ion Collider, the Japan Proton Accelerator Research Complex, E906 (Fermi Lab), and the Nuclotron-based Ion Collider Facility (Joint Institute for Nuclear Research). We show that the measurements of the asymmetries in those facilities can provide valuable information of the chiral-odd structure of the nucleon both in the valence and sea regions.
