1303.5849 (T. P. Djun et al.)

Gluonic plasma dominated early universe within fluid QCD    [PDF]

T. P. Djun, M. K. N. Patmawijaya, R. Utama, L. T. Handoko
An early universe dominated by gluonic plasma just before the hadronization is investigated. Using the fluid QCD framework, it is shown that during the QGP--hadron transition era the universe tends expanding exponentially with 40 e-fold scale factor, while the equation of state numerically yields $P \sim 1/5 \rho$. It is argued that the scenario supports the rather matter dominated hadronization phase, and agrees with the current flat and homogeneous universe.
