Hydrodynamic Flow at RHIC [PDF]

Acta Physica Hungarica, 2002
We review the apparently hydrodynamic behaviour of low transverse momentum particles (p_T < 1.5 GeV/c) produced in central and semicentral (b < 7 fm) heavy ion collisions at RHIC. We investigate the impact parameter dependence of various observables, elaborating on radial and elliptic flow and particle multiplicities.

Excitation functions of baryon anomaly and freeze-out properties at RHIC-PHENIX [PDF]

, 2007
The intermediate $p_T$ region (2 - 5 GeV/$c$) in central Au+Au collisions at RHIC has a rich physics content. The (anti)proton to pion ratio at the intermediate $p_T$ gives us a powerful tool to investigate the bulk properties of the hot and dense matter

Measurement of in-medium modification of energy-space structure of jets via γ and π0 triggered hadrons in Au+Au collisions at RHIC [PDF]

EPJ Web of Conferences
Since the discovery of the jet quenching at RHIC, the in-medium interaction of hard scattered partons with the nuclear medium created by highenergy heavy-ion collisions has been an excellent tool to understand not only the transport properties of the ...

TRANSVERSE SPIN AND RHIC [PDF]

Transversity 2005, 2006
The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory is the first accelerator facility that can accelerate, store and collide spin polarized proton beams. This development enables a physics program aimed at understanding how the spin of the proton results from its quark and gluon substructures.

RHIC optics and spin dynamics with snakes and rotators

Physical Review Accelerators and Beams, 2022
The operation of RHIC collider rings in polarized proton runs includes helical snakes, which allow for preserving polarization during acceleration to store energies.

Exclusive Vector Meson Production in Relativistic Heavy Ion Collisions [PDF]

, 1999
Exclusive vector meson production reactions such as $Au + Au \to Au + Au + V$, where $V=\rho, \omega, \phi$ or $J/\psi$ can proceed through photon-Pomeron and photon-meson interactions.

Elliptic flow at SPS and RHIC: from kinetic transport to hydrodynamics [PDF]

, 2000
Anisotropic transverse flow is studied in Pb+Pb and Au+Au collisions at SPS and RHIC energies. The centrality and transverse momentum dependence at midrapidity of the elliptic flow coefficient v_2 is calculated in the hydrodynamic and low density limits.

Commissioning of a first-order matched transition jump at the Brookhaven Relativistic Heavy Ion Collider

Physical Review Special Topics. Accelerators and Beams, 2004
When accelerating gold ions in the Relativistic Heavy Ion Collider (RHIC) the transition energy must be crossed. For this purpose, RHIC uses a set of correction quadrupoles and special power supplies which can reverse polarity in less than 40 ms.

The construction of the sPHENIX detector and status of its commissioning [PDF]

EPJ Web of Conferences
sPHENIX is the first new major detector at RHIC in over twenty years. It is designed for pioneering studies of the Quark Gluon Plasma and Cold QCD phenomena using high-pT jet and heavy flavor probes with a broad kinematic reach and a capability to take ...

Can hadronic rescattering explain the "jet quenching" at RHIC? [PDF]

, 2004
Recent RHIC data have shown novel nuclear modifications of moderate to high pt particle production in central Au+Au collisions, including a suppression of hadron production and a disappearance of back-to-back hadron pairs.
