The ratio of the production rate of yy pairs in the quark-gluon plasma to that in the hadron plasma is shoum to be much larger than the ratio of the production rate of p + p -pairs for the two plasma states. Hence the yy-pair production is more adequate to discriminate the plasma states.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
