Description
A consistent description of high pT particle suppression ($R_{AA}$) and azimuthal anisotropy $v_2$ has been a puzzle in the study of jet quenching, pointing to some non-perturbative native of jet transport. Event-by-event single inclusive jet suppression and azimuthal anisotropy are studied within the Linear Boltzmann Transport (LBT) model for jet propagation in QGP medium from 3+1D hydrodynamic evolution with fluctuating initial conditions. We demonstrate that LBT can describe both the single inclusive jet suppression and azimuthal anisotropy with a single adjustable parameter- effective strong coupling constant $\alpha_s$. This indicate observed jet quenching puzzle might be caused by non-perturbative phenomenon in hadronization at intermediate $p_T$. We also studied the energy and centrality dependence and the effect of fluctuation as compared to a smooth hydro evolution. A linear relationship is found between high $p_T$ jet anisotropy due to jet quenching and soft hadron anisotropy from hydrodynamic expansion
