title: "Figure 29a" of "Jet properties from dihadron correlations in p+p collisions at s**(1/2) = 200-GeV"

description: The $$ and $\bar{x_h}$ values with $p_{Ta}$ for two trigger $\pi^0$ momenta bins.
description: The properties of jets produced in $p$+$p$ collisions at $\sqrt{s}$ = 200 GeV are measured using the method of two particle correlations. The trigger particle is a leading particle from a large transverse momentum jet while the associated particle comes from either the same jet or the away-side jet. Analysis of the angular width of the near-side peak in the correlation function determines the jet fragmentation transverse momentum $j_T$. The extracted value, $\sqrt{}$ = 585 +/- 6(stat.) +/- 15(syst.) MeV/$c$, is constant with respect to the trigger particle transverse momentum, and comparable to the previous lower $\sqrt{s}$ measurements. The width of the away-side peak is shown to be a convolution of $j_T$ with the fragmentation variable, $z$, and the partonic transverse momentum, $k_T$. The $$ is determined through a combined analysis of the measured $\pi^0$ inclusive and associated spectra using jet fragmentation functions measured in $e^+$$e^-$ collisions. The final extracted values of $k_T$ are then determined to also be independent of the trigger particle transverse momentum, over the range measured, with value of $\sqrt{}$ = 2.68 +/- 0.07(stat.) +/- 0.34(syst.) GeV/$c$.

title: "Figure 14a" of "Measurement of charm and bottom production from semileptonic hadron decays in $p$$+$$p$ collisions at $\sqrt{s_{NN}}=200$ GeV"

description: Inclusive heavy-flavor-electron invariant yield from the refolded charm and bottom yields (closed squares [red]) compared to published data (closed circles [gray]).
description: Measurements of the differential production of electrons from open-heavy-flavor hadrons with charm and bottom-quark content in $p$ + $p$ collisions at $\sqrt{s}$ = 200 GeV are presented. The measurements proceed through displaced-vertex analyses of electron tracks from the semileptonic decay of charm and bottom hadrons using the PHENIX silicon-vertex detector. The relative contribution of electrons from bottom decays to inclusive heavy-flavor-electron production is found to be consistent with fixed-order-plus-next-to-leading-log perturbative-QCD calculations within experimental and theoretical uncertainties. These new measurements in $p$ + $p$ collisions provide a precision baseline for comparable forthcoming measurements in A + A collisions.

title: "Figure 1" of "Inclusive cross section and double helicity asymmetry for \pi^0 production in p+p collisions at sqrt(s)=200 GeV: Implications for the polarized gluon distribution in the proton"

description: The neutral pion production cross section at $\sqrt{s}$ = 200 GeV as a function of $p_T$ and the results of NLO pQCD calculations for theory scales $\mu$ = $p_T$/2, $p_T$, and $2p_T$. Additional 9.7% normalization uncertainty is not included.
description: The PHENIX experiment presents results from the RHIC 2005 run with polarized proton collisions at $\sqrt{s}$ = 200 GeV, for inclusive $\pi^0$ production at mid-rapidity. Unpolarized cross section results are given for transverse momenta $p_T$ = 0.5 to 20 GeV/$c$, extending the range of published data to both lower and higher $p_T$. The cross section is described well for $p_T$ &lt; 1 GeV/$c$ by an exponential in $p_T$, and, for $p_T$ &gt; 2 GeV/$c$, by perturbative QCD. Double helicity asymmetries $A_{LL}$ are presented based on a factor of five improvement in uncertainties as compared to previously published results, due to both an improved beam polarization of 50%, and to higher integrated luminosity. These measurements are sensitive to the gluon polarization in the proton, and exclude maximal values for the gluon polarization.

description: The PHENIX collaboration has measured $\phi$ meson production in $d$+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV using the dimuon and dielectron decay channels.
