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


Abstract in English

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 $6.75 < dN_{c}/deta < 20.2$. The hadronization temperature is $T = 179.5 pm 5$ (syst) MeV. Using Bjorkens 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.
