TL;DR: The measured azimuthal hit anisotropy is presented over a wide range of pseudorapidity for the first time at this energy, and calls into question the common assumption of longitudinal boost invariance over a large region of rapidity in RHIC collisions.

TL;DR: This Letter describes the measurement of the energy dependence of elliptic flow for charged particles in Au+Au collisions using the PHOBOS detector at the Relativistic Heavy Ion Collider, implying no sharp changes in the dynamics of particle production as a function of pseudorapidity or increasing beam energy.

TL;DR: In this article, the centrality dependence of the midrapidity charged particle multiplicity in heavy-ion collisions at different energies was investigated. But the results were not consistent with a value of x = 0.13.

TL;DR: In this article, a search that probes the local Galactic halo axion density using the Sikivie radio frequency cavity technique was carried out and it was shown that axions of Kim and Shifman, Vainshtein, and Zakharov contribute no more than 0.45 GeV cm 3 of mass density to the local dark matter halo over this mass range.

TL;DR: The PHOBOS experiment as discussed by the authors is capable of detecting charged particles over the full solid angle using a multiplicity detector and measuring identified charged particles near mid-rapidity in two spectrometer arms with opposite magnetic fields.
