Fluctuations of the transverse energy in Pb+Pb collisions and J/psi suppression
Joerg Huefner, Boris Z. Kopeliovich, Alberto Polleri
Abstract
The observed J/psi suppression in Pb+Pb collisions shows a drop at those large values of the transverse energy ET which arise from fluctuations. The validity of existing models for J/psi suppression can be extended into this domain of ET by introducing an ad hoc factor proportional to ET. We propose a formalism in which the influence of ET fluctuations on the J/psi suppression can be calculated and discuss the conditions under which the ad hoc factor is obtained.
