title: "Table 1" of "Nuclear effects on hadron production in d + Au and p + p collisions at s(NN)**(1/2) = 200-GeV."

description: Mean number of binary collisions, particpating nucleons from the Au nucleus, number of collisions per participating deuteron nucleon, and trigger bias corrections for the $d$+Au centrality bins.
description: PHENIX has measured the centrality dependence of mid-rapidity pion, kaon and proton transverse momentum distributions in $d$+Au and $p$+$p$ collisions at $\sqrt{s_{NN}}$ = 200 GeV. The $p$+$p$ data provide a reference for nuclear effects in $d$+Au and previously measured Au+Au collisions. Hadron production is enhanced in $d$+Au, relative to independent nucleon-nucleon scattering, as was observed in lower energy collisions. The nuclear modification factor for (anti) protons is larger than that for pions. The difference increases with centrality, but is not sufficient to account for the abundance of baryon production observed in central Au+Au collisions at RHIC. The centrality dependence in $d$+Au shows that the nuclear modification factor increases gradually with the number of collisions suffered by each participant nucleon. We also present comparisons with lower energy data as well as with parton recombination and other theoretical models of nuclear effects on particle production.

title: "Table 1" of "Production of Phi mesons at mid-rapidity in s**(1/2)(NN) = 200-GeV Au + Au collisions at RHIC."

description: Average number of participants and collisions in Au + Au reaction at RHIC for different centralities determined from a Glauber model.
description: We present the results of $\phi$ meson production in the $K^+ K^-$ decay channel from Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV as measured at mid-rapidity by the PHENIX detector at RHIC. Precision resonance centroid and width values are extracted as a function of collision centrality. No significant variation from the PDG accepted values is observed, contrary to some model predictions. The $\phi$ transverse mass spectra are fitted with a linear exponential function for which the derived inverse slope parameter is seen to be constant as a function of centrality. However, when these data are fitted by a hydrodynamic model the result is that the centrality-dependent freeze-out temperature and the expansion velocity values are consistent with the values previously derived from fitting identified charged hadron data. As a function of transverse momentum the collisions scaled peripheral-to-central yield ratio $R_{CP}$ for the $\phi$ is comparable to that of pions rather than that of protons. This result lends support to theoretical models which distinguish between baryons and mesons instead of particle mass for explaining the anomalous (anti)proton yield.
