Charm Correlation as a Diagnostic Probe of Quark Matter
Abstract
The use of correlation between two open-charm mesons is suggested to give information about the nature of the medium created in heavy-ion collisions. Insensitivity to the charm production rate is achieved by measuring normalized cumulant. The acollinearity of the D momenta in the transverse plane is a measure of the medium effect. Its dependence on nuclear size or ET provides a signature for the formation of quark matter.
