title: "Figure 18" of "Event Structure and Double Helicity Asymmetry in Jet Production from Polarized p+p Collisions at sqrt(s) = 200 GeV"

description: Reconstructed-jet $A_{LL}$ as a function of $p_T^{reco}$.
description: We report on event structure and double helicity asymmetry ($A_{LL}$) of jet production in longitudinally polarized $p$+$p$ collisions at $\sqrt{s}$ = 200 GeV. Photons and charged particles were measured by the PHENIX experiment at midrapidity $|\chi|$ &lt; 0.35 with the requirement of a high-momentum (&gt;2 GeV/$c$) photon in the event. Event structure, such as multiplicity, $p_T$ density and thrust in the PHENIX acceptance, were measured and compared with the $pythia$ event generator and $geant$ detector simulation. The shape of jets and the underlying event were well reproduced at this collision energy. For the measurement of jet $A_{LL}$, photons and charged particles were clustered with a seed-cone algorithm to obtain the cluster $p_T$ sum ($p^{reco}_T$). The effect of detector response and the underlying events on $p^{reco}_T$ was evaluated with the simulation. The production rate of reconstructed jets is satisfactorily reproduced with the NLO pQCD jet production cross section. For 4 &lt; $p^{reco}_T$ &lt; 12 GeV/$c$ with an average beam polarization of $\langle P \rangle $ = 49%, we measured $A_{LL}$ = -0.0014 $\pm$ 0.0037$^{stat}$ at the lowest $p^{reco}_T$ bin (4-5 GeV/$c$) and -0.0181 $\pm$ 0.0282$^{stat}$ at the highest $p^{reco}_T$ bin (10-12 GeV/$c$) with a beam polarization scale error of 9.4% and a $p_T$ scale error of 10%. Jets in the measured $p^{reco}_T$ range arise primarily from hard-scattered gluons with momentum fraction 0.02 &lt; $x$ &lt; 0.3 according to $pythia$. The measured $A_{LL}$ is compared with predictions that assume various $\Delta G(x)$ distributions based on the GRSV parameterization. The present result imposes the limit -1.1 $&lt;$ $\int_{0.02}^{0.30}dx\Delta G$($x$,$\mu^2$ = 1 GeV$^2$) $&lt;$ 0.4 at 95% confidence level or $\int_{0.02}^{0.30}dx\Delta G$($x$,$\mu^2$ = 1 GeV$^2$) $&lt;$ 0.5 at 99% confidence level.

description: Comparisons between the data and mixed event $M_{p_T}$ distributions for the representative 0-5% centrality classes. Also given are the residuals between the data and mixed events in units of standard deviations of the data points form the mixed event points.
description: Event-by-event fluctuations of the average transverse momentum of produced particles near mid-rapidity have been measured by the PHENIX Collaboration in $\sqrt{s_{NN}}$ = 200 GeV Au + Au and $p$ + $p$ collisions at the Relativistic Heavy Ion Collider. The fluctuations are observed to be in excess of the expectation for statistically independent particle emission for all centralities. The excess fluctuations exhibit a dependence on both the centrality of the collision and on the transverse momentum window over which the average is calculated. Both the centrality and $p_T$ dependence can be well reproduced by a simulation of random particle production with the addition of contributions from hard scattering processes.

description: Correlations between $p$ and $\bar{p}$ at transverse momenta typical of enhanced baryon production in Au+Au collisions are reported.
