Cold nuclear matter effects on ϕ meson and heavy flavor production in d + Au collisions at [formula omitted

Abstract

The PHENIX collaboration studies the cold nuclear matter effects by measuring the spectra of various probes over a wide range of transverse momentum and rapidity in d+Au collisions. The lepton decay channels of the ϕ meson and heavy flavor make them especially interesting probes since leptons interact only electromagnetically, thus retain information from their production phase. In 2008, the PHENIX collaboration collected ∼60 nb−1 from d+Au collisions at sNN=200 GeV. We report recent PHENIX results of ϕ meson and heavy flavor invariant production spectra and nuclear modification factors from this data set.
