title: "Figure 7a" of "Nonperturbative transverse-momentum-dependent effects in dihadron and direct photon-hadron angular correlations in $p+p$ collisions at $\sqrt{s}=200$ GeV"

description: The $p_{out}$ distributions are shown in several bins of $x_E$, integrated over a range of $p_T^{trig}$.
description: Dihadron and isolated direct photon-hadron angular correlations are measured in $p$+$p$ collisions at $\sqrt{s}$ = 200 GeV. The correlations are sensitive to nonperturbative initial-state and final-state transverse momentum $k_T$ and $j_T$ in the azimuthal nearly back-to-back region $\Delta\phi$ ∼ $\pi$. In this region, transverse-momentum-dependent evolution can be studied when several different hard scales are measured. To have sensitivity to small transverse momentum scales, nonperturbative momentum widths of $p_{out}$, the out-of-plane transverse momentum component perpendicular to the trigger particle, are measured. These widths are used to investigate possible effects from transverse-momentum-dependent factorization breaking. When accounting for the longitudinal momentum fraction of the away-side hadron with respect to the near-side trigger particle, the widths are found to increase with the hard scale; this is qualitatively similar to the observed behavior in Drell-Yan and semi-inclusive deep-inelastic scattering interactions. The momentum widths are also studied as a function of center-of-mass energy by comparing to previous measurements at $\sqrt{s}$ = 510 GeV. The nonperturbative jet widths also appear to increase with $\sqrt{s}$ at a similar $x_T$, which is qualitatively consistent to similar measurements in Drell-Yan interactions. To quantify the magnitude of any transverse-momentum-dependent factorization breaking effects, calculations will need to be performed to compare to these measurements.

title: "Figure 4a-1" of "Suppression of back-to-back hadron pairs at forward rapidity in d+Au Collisions at sqrt(s_NN)=200 GeV"

description: $J_{dA}$ versus $x^{frag}_{Au}$ for $d$+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV for different centrality classes.
description: Back-to-back hadron pair yields in $d$+Au and $p$+$p$ collisions at $\sqrt{s_{NN}}$ = 200 GeV were measured with the PHENIX detector at the Relativistic Heavy Ion Collider. Rapidity separated hadron pairs were detected with the trigger hadron at pseudorapidity $|\eta|$ &lt; 0.35 and the associated hadron at forward rapidity (deuteron direction, 3.0 &lt; $\eta$ &lt; 3.8). Pairs were also detected with both hadrons measured at forward rapidity; in this case the yield of back-to-back hadron pairs in $d$+Au collisions with small impact parameters is observed to be suppressed by a factor of 10 relative to $p$+$p$ collisions. The kinematics of these pairs is expected to probe partons in the Au nucleus with low fraction $x$ of the nucleon momenta, where the gluon densities rise sharply. The observed suppression as a function of nuclear thickness, $p_T$, and $\eta$ points to cold nuclear matter effects arising at high parton densities.
