Covariance of Antiproton Yield and Source Size in Nuclear Collisions

摘要

We confront for the first time the widely-held belief that combinedevent-by-event information from quark gluon plasma signals can reduce theambiguity of the individual signals. We illustrate specifically how themeasured antiproton yield combined with the information from pion-pion HBTcorrelations can be used to identify novel event classes.
