Chiral Magnetic Effect

The interplay of quantum anomalies with strong magnetic fields and vorticity in chiral systems could lead to novel transport phenomena, such as the chiral magnetic effect (CME), the chiral magnetic wave (CMW), and the chiral vortical effect (CVE). In high-energy nuclear collisions, these chiral effects may survive the expansion of a quark–gluon plasma fireball and be detected in experiments. The experimental searches for the CME, the CMW, and the CVE have aroused extensive interest over the past couple of decades. The main goal of this article is to review the latest experimental progress in the search for these novel chiral transport phenomena at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory and the Large Hadron Collider at CERN. Future programs to help reduce uncertainties and facilitate the interpretation of the data are also discussed.

Helium 3

The addition of a polarized 3He ion source for use at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory would enable a host of new measurements, particularly in the context of a planned eRHIC. We are developing such a source using metastability exchange optical pumping to polarize helium-3, which will be then transferred into RHIC’s Electron Beam Ion Source for ionization. We aim to deliver nuclear polarization of near 70%, and roughly 10[Formula: see text] doubly-ionized 3He[Formula: see text] ions will be created in each 20 [Formula: see text]sec pulse. We discuss the design of the source, and the status of its development.

Abstract Currently under construction at Brookhaven National Laboratory (BNL) is a large 3.8 km in circumference collider called the Relativistic Heavy Ion Collider (RHIC). The collider is capable of creating thousands of head-on collisions between beams of heavy ions, e.g., gold, or polarized protons traveling at nearly the speed of light Four experiments built along RHIC’s underground ring will measure the particles unleashed when the beams collide. This study deals with the PHENIX Detector which roughly fills an Experimental Hall with a floor area of 18.6 m by 15.8 m and a height of 14.3 m. The RHIC tunnel connects to the Experimental Hall through two opposite walls. The large tunnel openings are almost completely obstructed by massive steel plates which are part of the PHENIX Muon detector system. The Experimental Hall walls are all fixed except for one which is constructed from 1.7 m thick concrete blocks covering an opening which is 18 m wide by 14.0 m high. This block wall has a plug door which is designed to be unstacked so that large PHENIX detector systems can be transferred from the Experimental Hall into the adjacent Assembly Hall when required. The detector consists of several systems, each with its own role in detecting subatomic particles. Combustible gases such as ethane, isobutane, and methane are used in several of the detector systems. In particular, one of the systems called the Ring Imaging Cherenkov Detector (RICH) uses 80 m3 of pure ethane in two welded aluminum frames each with two large 0.127 mm thick aluminized KAPTON windows. The ethane gas is maintained at a pressure of a fraction of an inch of water above the ambient pressure. The work reported here deals with a safety analysis for a hypothetical accident scenario whereby the RICH windows are damaged and all the ethane inventory is released into the Experimental Hall, mixed with the ambient air and ignited. The objective of the analysis was to determine the scope of damage to the experiment and danger to personnel under various accident scenarios involving the extent of ethane gas release, the degree of mixing with ambient air and the mode of combustion. If all the ethane is assumed to be released and allowed to mix with the entire volume of air contained within the Experimental Hall, the calculations show that ignition of this mixture would not result in the collapse of the block wall.

Transport models have been very useful in studying the properties of the hot, dense matter that is created in relativistic heavy-ion collisions. We review here a Relativistic Transport (ART) Model and its applications in heavy ion collisions at beam energies below about 10 AGeV available from the Alternating Gradient Synchrotron at Brookhaven National Laboratory. The model allows one to study not only the reaction dynamics leading to the formation of superdense hadronic matter, but also to explore the effects due to the nuclear equation of state and the deformation/orientation of the colliding nuclei on the size and lifetime of the superdense matter. We also discuss the dependence of the central baryon and energy densities, the degree of thermalization, and the collective radial flow velocity of the superdense matter on the beam energy. We further review how the properties of the superdense hadronic matter can be determined from studying the collective flow of nucleons, pions and kaons in these collisions. We finally discuss the mechanisms for kaon production in relativistic heavy-ion collisions and review the progress in extracting the kaon in-medium properties from these collisions.

Highlights from Brookhaven National Laboratory (BNL) and experiments at the BNL Relativistic Heavy Ion Collider (RHIC) are presented for the years 2011–2013. This review is a combination of lectures which discussed the latest results each year at a three year celebration of the 50th anniversary of the International School of Subnuclear Physics in Erice, Sicily, Italy. Since the first collisions in the year 2000, RHIC has provided nucleus–nucleus and polarized proton–proton collisions over a range of nucleon–nucleon center-of-mass energies [Formula: see text] from 7.7 GeV to 510 GeV with nuclei from deuterium to uranium, most often gold. The objective was the discovery of the Quark Gluon Plasma, which was achieved, and the measurement of its properties, which were much different than expected, namely a "perfect fluid" of quarks and gluons with their color charges exposed rather than a gas. Topics including quenching of light and heavy quarks at large transverse momentum, thermal photons, search for a QCD critical point as well as measurements of collective flow, two-particle correlations and J/Ψ suppression are presented. During this period, results from the first and subsequent heavy ion measurements at the Large Hadron Collider (LHC) at CERN became available. These confirmed and extended the RHIC discoveries and have led to ideas for new and improved measurements.
