Long wavelength perfect fluidity from short distance jet transport in quark-gluon plasmas

TL;DR

This paper introduces a new framework connecting the long wavelength fluid properties and short distance jet transport in the quark-gluon plasma, successfully explaining experimental data and linking shear viscosity to jet quenching parameters.

Contribution

It develops a semi-Quark-Gluon-Monopole Plasma model integrated into CUJET3.0, bridging nonperturbative bulk properties with jet transport in the QGP.

Findings

Consistent description of RHIC and LHC data with CUJET3.0.

Quantitative relation between shear viscosity and jet transport parameter.

Temperature dependence of QGP's η/s ratio from near zero to higher T.

Abstract

We build a new phenomenological framework that bridges the long wavelength bulk viscous transport properties of the strongly-coupled quark-gluon plasma (sQGP) and short distance hard jet transport properties in the QGP. The full nonperturbative chromo-electric (E) and chromo-magnetic (M) structure of the near "perfect fluid" like sQGP in the critical transition region are integrated into a semi-Quark-Gluon-Monopole Plasma (sQGMP) model lattice-compatibly and implemented into the new CUJET3.0 jet quenching framework. All observables computed from CUJET3.0 are found to be consistent with available data at RHIC and LHC simultaneously. A quantitative connection between the shear viscosity and jet transport parameter is rigorously established within this framework. We deduce the $T=160-600$ MeV dependence of the QGP's $\eta/s$: its near vanishing value in the near $T_c$ regime is determined by the composition of E and M charges, it increases as $T$ rises, and its high $T$ limit is fixed by color screening scales.
