Azimuthal jet flavor tomography with CUJET2.0 of nuclear collisions at RHIC and LHC

Abstract

A perturbative QCD based jet tomographic Monte Carlo model, CUJET2.0, is presented to predict jet quenching observables in relativistic heavy ion collisions at RHIC/BNL and LHC/CERN energies. This model generalizes the DGLV theory of flavor dependent radiative energy loss by including multi-scale running strong coupling effects. It generalizes CUJET1.0 by computing jet path integrations though more realistic 2+1D transverse and longitudinally expanding viscous hydrodynamical fields contrained by fits to low $p_T$ flow data. The CUJET2.0 output depends on three control parameters, $({\alpha }_{max},f_E,f_M)$, corresponding to an assumed upper bound on the vacuum running coupling in the infrared and two chromo-electric and magnetic QGP screening mass scales $(f_E\mu (T),f_M\mu (T))$ where $\mu (T)$ is the 1-loop Debye mass. We compare numerical results as a function of ${\alpha }_{max}$ for pure and deformed HTL dynamically enhanced scattering cases corresponding to $(f_E=1,2,f_M=0)$ to data of the nuclear modification factor, $R_{AA}^f(p_T,\varphi ;\sqrt{s},b)$ for jet fragment flavors $f=\pi ,D,B,e$ at $\sqrt{s}=0.2-2.76$ ATeV c.m. energies per nucleon pair and with impact parameter $b=2.4,7.5$ fm. A ${\chi }^2$ analysis is presented and shows that $R_{AA}^{\pi }$ data from RHIC and LHC are consistent with CUJET2.0 at the ${\chi }^2/d.o.f<2$ level for ${\alpha }_{max}=0.23-0.30$. The corresponding $\hat{q}(E_{jet},T)/T^3$ effective jet transport coefficient field of this model is computed to facilitate comparison to other jet tomographic models in the literature. The predicted elliptic asymmetry, $v_2(p_T;\sqrt{s},b)$ is, however, found to significantly underestimated relative to RHIC and LHC data. We find the ${\chi }_{v_2}^2$ analysis shows that $v_2$ is very sensitive to allowing even as little as 10\% variations of the path averaged ${\alpha }_{max}$ along in and out of reaction plane paths.
