Transverse momentum spectra for charged hadrons and neutral pions in the range 1 GeV/c<p(T)<5 GeV/c have been measured by PHENIX experiment at RHIC Au+Au collisions root square[s(NN)] = 130 GeV. At high p(T) from peripheral nuclear are consistent with scaling p+p average number of binary nucleon-nucleon collisions. The central significantly suppressed when compared to binary-scaled expectation, also similarly collisions, indicating a novel nuclear-medium effect energies.
Many neutron star properties, such as the proton fraction, reflect symmetry energy contributions to equation of state that dominate when and densities differ strongly. To constrain these at suprasaturation densities, we measure spectra charged pions produced by colliding rare isotope tin (Sn) beams with isotopically enriched Sn targets. Using ratios pion measured high transverse momenta, deduce slope be $42<L<117\text{ }\text{ }\mathrm{MeV}$. This value is slightly lower but consistent $L$...

We present results for the charged-particle multiplicity distribution at midrapidity in Au-Au collisions square root of [s(NN)] = 130 GeV measured with PHENIX detector RHIC. For 5% most central we find dN(ch)/d eta(vertical line eta 0) 622+/-1(stat)+/-41(syst). The results, analyzed as a function centrality, show steady rise particle density per participating nucleon centrality.
Two-particle azimuthal correlation functions are presented for charged hadrons produced in Au+Au collisions at the Relativistic Heavy Ion Collider (sqrt [s(NN)]=130 GeV). The measurements permit determination of elliptic flow without event-by-event estimation reaction plane. extracted values (v2) show significant sensitivity to both collision centrality and transverse momenta emitted hadrons, suggesting rapid thermalization relatively strong velocity fields. When scaled by eccentricity zone...
Event shapes for Au + collisions at 11.4 GeV/c per nucleon were studied over nearly the full solid angle with E877 apparatus. The analysis was performed by Fourier expansion of azimuthal distributions transverse energy (ET) measured in different pseudorapidity intervals. For semicentral a pronounced event anisotropy is identified clear forward-backward anticorrelation. In forward interval up to 9% ET directed component. signal decreases peripheral and very central collisions.Received 12 May...

Two-pion correlations in square root[s(NN)] = 130 GeV Au+Au collisions at RHIC have been measured over a broad range of pair transverse momentum k(T) by the PHENIX experiment RHIC. The dependent radii are similar to results from heavy-ion 4.1, 4.9, and 17.3 GeV, whereas longitudinal radius increases monotonically with beam energy. ratio outwards sidewards (R(out)/R(side)) is consistent unity independent k(T).
The first measurement of energy produced transverse to the beam direction at Relativistic Heavy-Ion Collider Brookhaven National Laboratory is presented. midrapidity density per participating nucleon rises steadily with number participants, closely paralleling rise in charged-particle density, such that <E(T)>/<N(ch)> remains relatively constant as a function centrality. calculated via Bjorken's prescription for 2% most central Au+Au collisions square root[s(NN)] = 130 GeV least epsilon(Bj)...
Four different combinations of 4496Ru and 4096Zr nuclei, both as projectile target, were investigated at the same bombarding energy 400AMeV using a 4π detector. The degree isospin mixing between target nucleons is mapped across large portion phase space two isospin-tracer observables, number measured protons tritium to 3He yield ratio. experimental results show that global equilibrium not reached even in most central collisions. Quantitative measures stopping are extracted from data. They...
Recently, multiparticle-correlation measurements of relativistic $p/d/^{3}\mathrm{He}+\mathrm{Au}$, $p+\mathrm{Pb}$, and even $p+p$ collisions show surprising collective signatures. Here, we present beam-energy-scan two-, four-, six-particle angular correlations in $d+\mathrm{Au}$ at $\sqrt{{s}_{NN}}=200$, 62.4, 39, 19.6 GeV. We also two- four-particle $p+\mathrm{Au}$ $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. find the cumulant to be real valued for all four energies. that has...
