• Keywords: Particle identification

Identified mid-rapidity particle spectra of $\pi^{\pm}$, $K^{\pm}$, and $p(\bar{p})$ from 200 GeV p+p d+Au collisions are reported. A time-of-flight detector based on multi-gap resistive plate chamber technology is used for identification. The particle-species dependence the Cronin effect observed to be significantly smaller than that at lower energies. ratio nuclear modification factor ($R_{dAu}$) between protons $(p+\bar{p})$ charged hadrons ($h$) in transverse momentum range $1.2<{p_{T}}<3.0$ GeV/c measured $1.19\pm0.05$(stat)$\pm0.03$(syst) minimum-bias shows little centrality dependence. yield $(p+\bar{p})/h$ found a 2 Au+Au collisions, indicating alone not enough account relative baryon enhancement heavy ion RHIC.
