title: "Figure 11a" of "Observation of charge-dependent azimuthal correlations and possible local strong parity violation in heavy ion collisions"

description: Au+Au at 200 GeV. The correlations dependence on (p$_{t,\alpha}$ + p$_{t,\beta}$)/2 for centrality 30-50%. The shaded band indicates uncertainty associated with $v_{2}$ measurements and has been calculated using two- and four-particle cumulant results as the limits.
description: Parity-odd domains, corresponding to non-trivial topological solutions of the QCD vacuum, might be created during relativistic heavy-ion collisions. These domains are predicted to lead to charge separation of quarks along the orbital momentum of the system created in non-central collisions. To study this effect, we investigate a three particle mixed harmonics azimuthal correlator which is a $\mathcal{P}$-even observable, but directly sensitive to the charge separation effect. We report measurements of this observable using the STAR detector in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 and 62 GeV. The results are presented as a function of collision centrality, particle separation in rapidity, and particle transverse momentum. A signal consistent with several of the theoretical expectations is detected in all four data sets. We compare our results to the predictions of existing event generators, and discuss in detail possible contributions from other effects that are not related to parity violation.

title: "Figure 13" of "Observation of charge-dependent azimuthal correlations and possible local strong parity violation in heavy ion collisions"

description: Three-particle correlator in Au+Au and Cu+Cu collisions compared to HIJING calculations shown as thick lines. All three particles are taken in the main TPC region, |$\eta$| &lt; 1.0. The correlator has been scaled with number of participants and are plotted versus number of participants. In this representation HIJING results for Au+Au and Cu+Cu collisions coincide in the region of overlap.

title: "Figure 14" of "Observation of charge-dependent azimuthal correlations and possible local strong parity violation in heavy ion collisions"

description: $\langle cos(\phi_{\alpha} + \phi_{\beta} − 2\Psi_{RP})\rangle$ calculated for 200 GeV Au+Au events with event generators HIJING (with and without an “elliptic flow afterburner”), UrQMD, and MEVSIM. Blue symbols mark opposite-charge correlations, and red are same-charge. Solid stars represent the values from the data to facilitate comparison. Acceptance cuts of 0.15 &lt; p$_{t}$ &lt; 2 GeV/c and |$\eta$| &lt; 1.0 were used in all cases. For MEVSIM, HIJING, and UrQMD points the true reaction plane from the generated event was used for $\Psi_{RP}$ . Thick solid lighter colored lines represent possible non-reactionplane dependent contribution from many-particle clusters as estimated by HIJING and discussed in Section VII A. Corresponding estimates from UrQMD are about factor of two smaller.

description: $\langle cos(\phi_{\alpha}+\phi_{\beta}−2\Psi_{RP})\rangle$ in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV calculated using Eq. 2. The thick solid (Au+Au) and dashed (Cu+Cu) lines represent HIJING calculations of the contributions from 3-particle correlations. Shaded bands represent uncertainty from the measurement of $v_{2}$. Collision centrality increases from left to right.

title: "Figure 2" of "Azimuthal anisotropy and correlations in the hard scattering regime at RHIC."

description: $v_{2}$($p_{T}$) for different collision centralities. The errors are statistical only. The systematic uncertainties, which are highly correlated point-to-point, are $^{+5}_{-20}%$.
description: Azimuthal anisotropy ($v_{2}$) and two-particle angular correlations of high $p_{T}$ charged hadrons have been measured in Au+Au collisions at $\sqrt{s_{NN}}$=130 GeV for transverse momenta up to 6 GeV/c, where hard processes are expected to contribute significantly. The two-particle angular correlations exhibit elliptic flow and a structure suggestive of fragmentation of high $p_{T}$ partons. The monotonic rise of $v_{2}$($p_{T}$) for $p_{T}$&lt;2 GeV/c is consistent with collective hydrodynamical flow calculations. At $p_{T}$&gt;3 GeV/c a saturation of $v_{2}$ is observed which persists up to $p_{T}$=6 GeV/c.

The data are compared with hydro+pQCD calculations [9] assuming the initial gluon density $dN^{g}/dy$ = 1000 (dashed line), 500 (dotted line), and 200 (dashed-dotted line). Also shown are pure hydrodynamical calculations [16] (solid line).

description: (a) The pair mass distribution, (b) pair $p){T}$ , (c) pair rapidity and (d) pair cos($\theta′$) distributions. The data (points) are compared with predictions from the EPA (solid histogram) and lowest-order QED (dashed histogram) calculations. The error bars include both statistical and systematic errors.
description: We present the first data on $e^{+}e^{−}$ pair production accompanied by nuclear breakup in ultra-peripheral gold-gold collisions at a center of mass energy of 200 GeV per nucleon pair. The nuclear breakup requirement selects events at small impact parameters, where higher-order corrections to the pair production cross section should be enhanced. We compare the pair kinematic distributions with two calculations: one based on the equivalent photon approximation, and the other using lowest-order quantum electrodynamics (QED); the latter includes the photon virtuality. The cross section, pair mass, rapidity and angular distributions are in good agreement with both calculations. The pair transverse momentum, $p_{T}$, spectrum agrees with the QED calculation, but not with the equivalent photon approach. We set limits on higher-order contributions to the cross section. The $e^{+}$ and $e^{−}$ $p_{T}$ spectra are similar, with no evidence for interference effects due to higher-order diagrams.

title: Therapeutic Artworks

description: This collection includes over 900 pieces of art that were created by patients at the Atascadero State Hospital (ASH) in the mid-1950’s.  The artists were under the treatment of Albert R. Vercoutere who used the technique of providing photos from magazines for the patients to use as inspiration for their own artwork. Although not trained in the use of art therapy and during a time when art therapy was a new approach, Vercoutere often utilized art as a mechanism for working with his patients. The artwork was created during a time when psychotropic drugs were not yet available as treatment options for mental health patients.
