title: "Fig2a" of "Medium modification of jet fragmentation in Au+Au collisions at sqrt(s_NN)=200 GeV measured in direct photon-hadron correlations"

description: Integrated per-trigger yields and I_AA vs xi
description: BNL-RHIC. The jet fragmentation function is measured with direct photon-hadron correlations inp+pandAu+Au collisions at√sNN= 200 GeV. ThepTof the photon is an excellent approximation to theinitialpTof the jet and the ratiozT=phT/pγTis used as a proxy for the jet fragmentation function.A statistical subtraction is used to extract the direct photon-hadron yields in Au+Au collisionswhile a photon isolation cut is applied inp+p.IAA, the ratio of jet fragment yield in Au+Au tothat inp+p, indicates modification of the jet fragmentation function.Suppression, most likely dueto energy loss in the medium, is seen at highzT. The fragment yield at lowzTis enhanced at largeangles. Such a trend is expected from redistribution of the lost energy into increased production oflow-momentum particles.

title: "fig1" of "Measurement of charged pion double spin asymmetries at midrapidity in longitudinally polarized $p+p$ collisions at $\sqrt{s}=510$ GeV"

description: Double-spin asymmetries $A_{LL}$ as a function of transverse momentum for positive and negative pions.
description: BNL-RHIC. The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the longitudinal double spin asymmetries, $A_{LL}$, for charged pions at midrapidity ($|\eta|&lt;$~0.35) in longitudinally polarized $p$$+$$p$ collisions at $\sqrt{s}=510$~GeV. These measurements are sensitive to the gluon spin contribution to the total spin of the proton in the parton momentum fraction $x$ range between 0.04 and 0.09. One can infer the sign of the gluon polarization from the ordering of pion asymmetries with charge alone. The asymmetries are found to be consistent with global quantum-chromodynamics fits of deep-inelastic scattering and data at $\sqrt{s}=200$~GeV, which show a nonzero positive contribution of gluon spin to the proton spin.

description: BNL-RHIC. We report new STAR measurements of mid-rapidity yields for the $\Lambda$, $\bar{\Lambda}$, $K^0_S$, $\Xi^-$, $\bar{\Xi}^+$, $\Omega^-$, $\bar{\Omega}^+$ particles in Cu+Cu collisions at $\sqrt{s_{NN}} = 200$ GeV, and mid-rapidity yields for the $\Lambda$, $\bar{\Lambda}$, $K^0_S$ particles in Au+Au at $\sqrt{s_{NN}} = 200$ GeV. We show that at a given number of participating nucleons, the production of strange hadrons is higher in Cu+Cu collisions than in Au+Au collisions at the same center-of-mass energy.
