Energy Deposition in High-Energy Proton-Nucleus Collisions

The PHOBOS perspective on discoveries at RHIC

“…Although the measurements do not include the bulk of the net baryons, the data can constrain the shape of the distributions substantially. The BRAHMS analysis finds that the average rapidity loss of the net baryons in central Au+Au collisions at √ s NN =200 GeV is ∆y ∼2 units [139], which is consistent with values extracted from p+A data at lower energy [140,141]. When translated into "available" energy, i.e.…”

“…The nature of baryon/anti-baryon production itself is the subject of much interest, with theoretical conjecture addressing a range of possible mechanisms from string fragmentation [8], to exotic mechanisms involving Quantum Chromo Dynamics (QCD) domain walls [9]. The physical nature of the entity which carries baryon number, and the means by which baryon number is transported over a large rapidity gap into the mid-rapidity region are also subjects of considerable experimental and theoretical interest [10,11,12].…”
