Available in PDF, EPUB and Kindle. Book excerpt: The anomalous suppression of J/[psi] production in Pb-Pb collisions at 158 GeV observed by the NA50 Collaboration can be explained as due to the occurrence of a new phase of strong J/[psi] absorption, which sets in when the local energy density exceeds about 3.4 GeV/fm[sup 3]. The peculiar behavior of the[psi][sup']/[psi] ratio in[ital p]-A and nucleus-nucleus collisions can be understood as due to approximately equal[psi]-N and[psi][sup']-N absorption cross sections, but greater absorption cross sections for[psi][sup'] than J/[psi] with regard to absorption by soft particles and matter in the new phase.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: J/psi and psi' produced in high-energy heavy-ion collisions are absorbed by their collisions with nucleons and produced soft particles, leading to two distinct absorption mechanisms. The signature of absorption by produced soft particles, as revealed by psi' production data, consists of a gap and a change of the slope in going from the pA line to the nucleus-nucleus line when we make a semi-log plot of the survival probability as a function of the path length. Using this signature, we find from the J/psi production data in pA, O-Cu, O-U, and S-U collisions that the degree of J/psi absorption by produced soft particles is small and cannot account for the J/psi data in Pb-Pb collisions. The anomalous suppression of J/psi production in Pb-Pb collisions can be explained as due to the occurrence of a new phase of strong J/psi absorption, which sets in when the local energy density exceeds about 3.4 GeV/fm3. To probe the chemical content of the new phase, we propose to study the abundance of open-charm mesons and charm hyperons which depends sensitively on the quark chemical potential.

Available in PDF, EPUB and Kindle. Book excerpt: A comparison of the relative yields of Upsilon resonances in the mu(+) mu( - ) decay channel in PbPb and pp collisions at a centre-of-mass energy per nucleon pair of 2.76 TeV, is performed with data collected with the CMS detector at the LHC. Using muons of transverse momentum above 4 GeV/c and pseudorapidity below 2.4, the double ratio of the Upsilon(2S) and Upsilon(3S) excited states to the Upsilon(1S) ground state in PbPb and pp collisions, (Upsilon(2S+3S)/Upsilon(1S)[PbPb])/(Upsilon(2S+3S)/Upsilon(1S)[pp]), is found to be 0.31 - 0.15 + 0.19 (stat.) +/- 0.03 (syst.). The probability to obtain the measured value, or lower, if the true double ratio is unity, has been calculated to be less than 1%.
