Abstract

With proton-proton collisions at PHENIX a variety of direct channels are used to probe the proton substructure. Of the many channels available at PHENIX, charged pion measurements are expected to have sensitivity of Δg and thus help in the global analysis that will constrain it. We present a measurement of mid-rapidity charged pion production double longitudinal spin asymmetries (ALL) at the pT range of 5–10GeV/c at collision energies of [formula]. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
