Abstract: (arXiv)

We report transverse momentum (

p_{T} \leq15

GeV/

c

) spectra of

\pi^{\pm}

,

K^{\pm}

,

p

,

\bar{p}

,

K_{S}^{0}

, and

\rho^{0}

at mid-rapidity in p+p and Au+Au collisions at

\sqrt{s_{_{NN}}}

= 200 GeV. Perturbative QCD calculations are consistent with

\pi^{\pm}

spectra in p+p collisions but do not reproduce

K

and

p(\bar{p})

spectra. The observed decreasing antiparticle-to-particle ratios with increasing

p_T

provide experimental evidence for varying quark and gluon jet contributions to high-

p_T

hadron yields. The relative hadron abundances in Au+Au at

p_{T}{}^{>}_{\sim}8

GeV/

c

are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.
