Geometric Parameterization of J/Ψ Absorption in Heavy Ion Collisions
We calculate the survival probability of J/Ψ particles in various colliding systems using a Glauber model. An analysis of recent data[1] has reported a J/Ψ-nucleon breakup cross section of 6.2±0.7 mb[2] derived from an exponential fit to the ratio of J/Ψ to Drell-Yan yields as a function of a simple, linearly-averaged mean path length 〈L〉 through the nuclear medium. Our calculations indicate th...
متن کاملAbsorption and J/ψ Suppression in Heavy Ion Collisions
We discuss the J/ψ suppression in the framework of multiple collision models. From the analysis of the Pb–Pb NA50 data we conclude that the strength of the absorption has increased, but we find no clear evidence for the formation of the quark–gluon plasma. 2 The suppression of the J/ψ production in nucleus–nucleus collisions was proposed, more than ten years ago, by Matsui and Satz [1] as a sig...

متن کاملDileptons in Heavy-Ion Collisions
Due to their penetrating nature, dileptons are a valuable probe for the properties of the hot and/or dense medium created in relativistic heavy-ion collisions. Dilepton invariant-mass spectra provide direct access to the properties of the electromagnetic current-correlation function in strongly interacting matter. In this paper an overview is given of our current theoretical understanding of th...
متن کاملHeavy ion collisions and cosmology
There are interesting parallels between the physics of heavy ion collisions and cosmology. Both systems are out-ofequilibrium and relativistic fluid dynamics plays an important role for their theoretical description. From a comparison one can draw interesting conclusions for both sides. For heavy ion physics it could be rewarding to attempt a theoretical description of fluid perturbations simil...
