Description
In ultra-relativistic heavy-ion collisions at RHIC and LHC, high energy jet fragments' nuclear modification factor ($R_{AA}$) and azimuthal anisotropy ($v_2$) provide a stringent set of observables in constraining the parton-medium interactions. We present a new jet quenching framework, CUJET3.0, that is shown to simultaneously account for both high $p_T$ single inclusive hadron’s $R_{AA}$ and $v_2$ at both RHIC and LHC energies. CUJET3.0 generalizes our previous perturbative QCD (pQCD) based CUJET2.0 model by incorporating non-perturbative lattice QCD constraints on the suppression of color-electric scatterings and the enhancement of scatterings due to emergent color-magnetic monopoles near the QCD confinement transition temperature. Our analysis provides a novel connection between the jet transport coefficient controlling hard jet quenching observables and the bulk soft ``perfect fluidity'' of quark-gluon plasmas. We further present predictions of high $p_T$ open heavy flavor’s $R_{AA}$ and $v_2$ from CUJET3.0, which can be tested in future RHIC measurements to complement the light quark sector.
