Evidence for hadronic deconfinement in $\bar{p}$-p collisions at 1.8 TeV

Abstract

We have measured deconfined hadronic volumes, $4.4<V<13.0$ fm${}^3$, produced by a one dimensional (1D) expansion. These volumes are directly proportional to the charged particle pseudorapidity densities $6.75<d{N}_c/d\eta <20.2$. The hadronization temperature is $T=179.5\pm 5$ (syst) MeV. Using Bjorken's 1D model,the hadronization energy density is ${\epsilon }_F=1.10\pm 0.26$ (stat) GeV/fm${}^3$ corresponding to an excitation of $24.8\pm 6.2$ (stat) quark-gluon degrees of freedom.
