The azimuthal anisotropy of parton energy loss in non-central heavy-ion collisions can lead to jet anisotropy, which can provide insight into the path-length dependence of jet quenching. Jet anisotropy flow in this study is investigated within the Linear Boltzmann Transport model, in which the dynamical evolution of the QGP is simulated with fully fluctuating event-by-event initial conditions....

Jet interactions with the hot QCD medium created in heavy-ion collisions are conventionally assessed by measuring the modification of the distributions of jet observables with respect to a proton-proton baseline. However, the steeply falling production spectrum introduces a strong bias toward small energy losses that obfuscates a direct interpretation of the impact of medium effects in the...

The suppression of large transverse momentum ($p_{\rm T}$) hadrons and the yield of dihadrons and $\gamma$-hadrons in relativistic heavy-ion collisions is a direct consequence of the parton energy loss induced by parton-medium interactions, whose strength is described by the jet transport coefficient $\hat{q}$ of the quark-gluon plasma (QGP). Because dihadrons and $\gamma$-hadrons have...

We propose a method qualitatively connecting the hadron nuclear modification factor to its quark component nuclear modification factor. We give a systematic study of the connection in the frame of the numerical Monte-Carlo model PACIAE. It turns out that the hadron nuclear modification factor is usually smaller than that of its quark component. The flavor (mass) ordering of the nuclear...

The unique forward coverage of the LHCb spectrometer allows the valence quark distributions of protons and nuclei to be probed with unprecedented precision. In this high-x region, both the flavour content and structure of the nucleon's parton distribution functions remain relatively poorly known. New LHCb measurements of Z+charm jet production could be indicative of a valence-like...

Under the assumption of same background but different magnetic fields, isobaric collisions are believed to be an effective way to measure the anomalous chiral effects. The isobaric program at the Relativistic Heavy Ion Collider (RHIC) has been done by colliding $_{44}^{96}\rm{Ru}+_{44}^{96}\rm{Ru}$ and $_{40}^{96}\rm{Zr}+_{40}^{96}\rm{Zr}$, however, it reveals that the chiral magnetic effect...
