This is the Report of a Committee charged by Dr. John Marburger, Director of Brookhaven National Laboratory, to review potentially catastrophic processes that might be initiated by heavy ion collisions at the Relativistic Heavy Ion Collider. Our conclusion is that the candidate mechanisms for catastrophe scenarios at RHIC are firmly excluded by existing(More)

A measurement of two-particle correlations with a high transverse momentum trigger particle (p trig T > 2:5 GeV=c) is presented for Au þ Au collisions at ffiffiffiffiffiffiffiffi s NN p ¼ 200 GeV over the uniquely broad longitudinal acceptance of the PHOBOS detector (À4 < Á < 2). A broadening of the away-side azimuthal correlation compared to elementary(More)
Based on trends seen at lower energies we " predict " the multiplicities and pseudorapidity distributions of particle density and elliptic flow that will be seen in PbPb and pp collisions at the LHC. We argue that, if these predictions turn out to be correct, either these quantities are insensitive to the state of matter created in high energy heavy ion(More)
We present the first measurements of the pseudorapidity distribution of primary charged particles in Cu+Cu collisions as a function of collision centrality and energy, sqrt[s_{NN}]=22.4, 62.4, and 200 GeV, over a wide range of pseudorapidity, using the PHOBOS detector. A comparison of Cu+Cu and Au+Au results shows that the total number of produced charged(More)

We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at √ s NN = 200 GeV. The evolution of the spectra for transverse momenta p T from 0.25 to 5 GeV/c is studied as a function of collision centrality over a range from 65 to 344 participating nucleons. We find a significant change of the spectral shape between p¯ p and(More)
We discuss speculative disaster scenarios inspired by hypothetical new fundamental processes that might occur in high energy relativistic heavy ion collisions. We estimate the parameters relevant to black hole production ; we find that they are absurdly small. We show that other accelerator and (especially) cosmic ray environments have already provided far(More)
