Anisotropic Jet Quenching in semi-Quark-Gluon Plasmas with Magnetic Monopoles

ORAL

Abstract

We present a new jet quenching framework, CUJET3.0, that is shown to simultaneously account for both the high $p_T$ single inclusive hadron suppression $R_{AA}$ and its azimuthal anisotropy $v_2$ in heavy ion collisions at both RHIC and LHC energies. CUJET3.0 generalizes our previous pQCD/HTL based CUJET2.0 model that couples running coupling DGLV jet energy loss to (2+1)D viscous hydrodynamic fluids, and it includes two new nonperturbative effects in the QCD transition temperature range $T\sim \rm 140-250$ MeV: (1) the Polyakov loop suppression of color-electric scattering (aka ``semi-QGP'' of Pisarski et al) and (2) the enhancement of scattering due to emergent magnetic monopoles near $T_c$ (aka ``magnetic scenario'' of Liao and Shuryak). The parameters of the model are constrained by lattice QCD data. We find that the CUJET3.0 jet transport coefficient $\hat{q}(E,T)/T^3$ peaks near $T_c$ by a factor $\sim 4$ above previous perturbative pQCD/HTL estimates, approaching hybrid AdS/SYM holography of Liu et al, but it has very strong nonconformal $E$ and $T$ dependence up to $T\sim 400$ MeV. Extrapolating down to $E=2$ GeV, we find a striking new connection between bulk perfect fluidity with $\eta/s\sim 0.1$ near $T_c$ and high $p_T$ high $T$ perturbative jet quenching.
