We report transverse momentum (p_{T}≤15 GeV/c) spectra of π^{±}, K^{±}, p, p[over ¯], K_{S}^{0}, and ρ^{0} at midrapidity in p+p and Au+Au collisions at sqrt[s_{NN}]=200 GeV. Perturbative QCD calculations are consistent with π^{±} spectra in p+p collisions but do not reproduce K and p(p[over ¯]) 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}≳8 GeV/c are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.

We report new STAR measurements of midrapidity yields for the Λ, Λ[over ¯], K_{S}^{0}, Ξ^{-}, Ξ[over ¯]^{+}, Ω^{-}, Ω[over ¯]^{+} particles in Cu+Cu collisions at sqrt[s_{NN}]=200 GeV, and midrapidity yields for the Λ, Λ[over ¯], K_{S}^{0} particles in Au+Au at sqrt[s_{NN}]=200 GeV. We show that, at a given number of participating nucleons, the production of strange hadrons is higher in Cu+Cu collisions than in Au+Au collisions at the same center-of-mass energy. We find that aspects of the enhancement factors for all particles can be described by a parametrization based on the fraction of participants that undergo multiple collisions.

We report the first measurement of the parity-violating single-spin asymmetries for midrapidity decay positrons and electrons from W+ and W- boson production in longitudinally polarized proton-proton collisions at sqrt[s]= 500 GeV by the STAR experiment at RHIC. The measured asymmetries, A(L)(W+)=-0.27 ± 0.10(stat.) ± 0.02(syst.) ± 0.03(norm.) and A(L)(W-)= 0.14 ± 0.19(stat.) ± 0.02(syst.) ± 0.01(norm.), are consistent with theory predictions, which are large and of opposite sign. These predictions are based on polarized quark and antiquark distribution functions constrained by polarized deep-inelastic scattering measurements.

The production of e;{+}e;{-} pairs for m_{e;{+}e;{-}}<0.3 GeV/c;{2} and 1<p_{T}<5 GeV/c is measured in p+p and Au+Au collisions at sqrt[s_{NN}]=200 GeV. An enhanced yield above hadronic sources is observed. Treating the excess as photon internal conversions, the invariant yield of direct photons is deduced. In central Au+Au collisions, the excess of the direct photon yield over p+p is exponential in transverse momentum, with an inverse slope T=221+/-19;{stat}+/-19;{syst} MeV. Hydrodynamical models with initial temperatures ranging from T_{init} approximately 300-600 MeV at times of approximately 0.6-0.15 fm/c after the collision are in qualitative agreement with the data. Lattice QCD predicts a phase transition to quark gluon plasma at approximately 170 MeV.

Nuclear collisions recreate conditions in the universe microseconds after the Big Bang. Only a very small fraction of the emitted fragments are light nuclei, but these states are of fundamental interest. We report the observation of antihypertritons-comprised of an antiproton, antineutron, and antilambda hyperon-produced by colliding gold nuclei at high energy. Our analysis yields 70 +/- 17 antihypertritons ($${}_{\overline{\Lambda }};{3}\overline{\mathrm{H}}$$) and 157 +/- 30 hypertritons ($${}_{\Lambda };{3}\mathrm{H}$$). The measured yields of $${}_{\Lambda };{3}\mathrm{H}$$($${}_{\overline{\Lambda }};{3}\overline{\mathrm{H}}$$) and (3)He ((3)$$\overline{\mathrm{He}}$$) are similar, suggesting an equilibrium in coordinate and momentum space populations of up, down, and strange quarks and antiquarks, unlike the pattern observed at lower collision energies. The production and properties of antinuclei, and nuclei containing strange quarks, have implications spanning nuclear/particle physics, astrophysics, and cosmology.

The momentum distribution of electrons from semileptonic decays of charm and bottom quarks for midrapidity |y|<0.35 in p+p collisions at square root of s=200 GeV is measured by the PHENIX experiment at the Relativistic Heavy Ion Collider over the transverse momentum range 2<pT<7 GeV/c. The ratio of the yield of electrons from bottom to that from charm is presented. The ratio is determined using partial D/D-->e(+/-)K(-/+)X (K unidentified) reconstruction. It is found that the yield of electrons from bottom becomes significant above 4 GeV/c in pT. A fixed-order-plus-next-to-leading-log perturbative quantum chromodynamics calculation agrees with the data within the theoretical and experimental uncertainties. The extracted total bottom production cross section at this energy is sigma(bb)=3.2(-1.1)(+1.2)(stat)(-1.3)(+1.4)(syst)mub.

For Au+Au collisions at 200 GeV, we measure neutral pion production with good statistics for transverse momentum, p_{T}, up to 20 GeV/c. A fivefold suppression is found, which is essentially constant for 5<p_{T}<20 GeV/c. Experimental uncertainties are small enough to constrain any model-dependent parametrization for the transport coefficient of the medium, e.g., q[over ;] in the parton quenching model. The spectral shape is similar for all collision classes, and the suppression does not saturate in Au+Au collisions.

Neutral pion transverse momentum (p_{T}) spectra at midrapidity (|y| less, similar0.35) were measured in Cu+Cu collisions at sqrt[s_{NN}]=22.4, 62.4, and 200 GeV. Relative to pi;{0} yields in p+p collisions scaled by the number of inelastic nucleon-nucleon collisions (N_{coll}) the pi;{0} yields for p_{T} greater, similar2 GeV/c in central Cu+Cu collisions are suppressed at 62.4 and 200 GeV whereas an enhancement is observed at 22.4 GeV. A comparison with a jet-quenching model suggests that final state parton energy loss dominates in central Cu+Cu collisions at 62.4 and 200 GeV, while the enhancement at 22.4 GeV is consistent with nuclear modifications in the initial state alone.

Yields for J/psi production in Cu+Cu collisions at sqrt[s_{NN}]=200 GeV have been measured over the rapidity range |y|<2.2 and compared with results in p+p and Au+Au collisions at the same energy. The Cu+Cu data offer greatly improved precision over existing Au+Au data for J/psi production in collisions with small to intermediate numbers of participants, in the range where the quark-gluon plasma transition threshold is predicted to lie. Cold nuclear matter estimates based on ad hoc fits to d+Au data describe the Cu+Cu data up to N_{part} approximately 50, corresponding to a Bjorken energy density of at least 1.5 GeV/fm;{3}.

We present azimuthal angle correlations of intermediate transverse momentum (1-4 GeV/c) hadrons from dijets in Cu+Cu and Au+Au collisions at sqrt[s_{NN}]=62.4 and 200 GeV. The away-side dijet induced azimuthal correlation is broadened, non-Gaussian, and peaked away from Deltavarphi=pi in central and semicentral collisions in all the systems. The broadening and peak location are found to depend upon the number of participants in the collision, but not on the collision energy or beam nuclei. These results are consistent with sound or shock wave models, but pose challenges to Cherenkov gluon radiation models.
