Description

Jet anisotropy can provide insight into the path-length dependence of jet quenching and closely relate to the bulk anisotropy in high energy heavy-ion collisions. We show a weak dependence of colliding energy and jet $p_{T}$ for inclusive jet anisotropy $v^{2}_{jet}$ at different centrality classes within the linear Boltzmann jet transport model coupled with the dynamic evolution of the QGP provided by the 3+1D CLVisc hydrodynamic model with fully fluctuating event-by-event initial conditions. By studying the hard-soft tomography, jet anisotropy follows a similar dependence on the system size as the bulk anisotropy does, and an approximately linear correlation between $v^{2}_{jet}$ and bulk $v_{2}$ is observed. In the meantime, jet triangle flow coefficient $v^{3}_{jet}$ shows a small but not vanishing value due to the initial fluctuation and jet quenching.
