摘要

From our previously obtained shear viscosity to entropy density ratio (eta/s) in the framework of clustering of color sources (the color string percolation model, CSPM), we calculate the jet quenching parameter (q) over cap and trace anomaly Delta = (epsilon - 3p)/T-4 as a function of temperature. It is shown that the scaled (q) over cap /T-3 is in agreement with the recent JET Collaboration estimates. The inverse of eta/s is found to represent Delta. The results for Delta are in excellent agreement with lattice quantum chromodynamics (LQCD) simulations. From the trace anomaly and energy density is an element of, the equation of state is obtained as a function of temperature and compared with LQCD simulations. It is possible that there is a direct connection between the eta/s and Delta. Thus the estimate of transport coefficient eta/s provides (q) over cap and Delta as a function of temperature. Both Delta and eta/s describe the transition from a strongly coupled quark-gluon plasma (QGP) to a weakly coupled QGP.
