Oral report
The energy loss of jets (jet quenching) is one of the most important signatures of the deconfined state of quarks and gluons (Quark-Gluon Plasma) created in Pb--Pb collisions at the LHC. The measurement of jets recoiling from a trigger hadron uniquely enables the exploration of medium-induced modification of jet production. Jet deflection via multiple soft scatterings with the medium...

Oral report
Jet quenching has long been regarded as one of the most important signatures for the discovery of Quark-Gluon Plasma created in heavy-ion collisions. Despite significant efforts, separate identification of quark and gluon jet quenching has remained as a challenge. We illustrate for the first time that energetic $J/\psi$ production can be served as a unique probe to the gluon jet quenching...

Oral report
When an energetic parton traverses the hot QCD medium, it may suffer multiple scattering and energy losses. The medium-induced gluon radiation for a massive quark will be suppressed relative to that of a light quark due to the dead-cone effect. The development of new declustering techniques of jet evolution makes a direct study of the dead-cone effect in the QCD medium possible for the first...

Oral report
In this work, we study the impact of jet quenching on $p_{T}$ dispersion($p_{T}D$) of inclusive jets ($R=0.2$) in Pb+Pb collisions at $\sqrt{s}=2.76$~TeV.
The partonic spectrum in the initial hard scattering of elementary collisions are obtained by an event generator POWHEG+PYTHIA, which matches the next-to-leading (NLO) matrix elements with parton showering, and energy loss of fast parton...

Two-particle correlations with $V^{0}$ $(K^{0}_{S}, \Lambda/\bar\Lambda)$ and charged hadrons as trigger particles of transverse momentum
$8 < p_\mathrm{T,trig}< 16$ GeV/c, and associated charged particles of $1 < p_\mathrm{T,assoc}< 8$ GeV/c, are studied at mid-rapidity in pp and most central Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV with the ALICE detector at the LHC. ...

We carry out the first theoretical investigation on
yields and the hardest parton splitting of large-radius jets
reclustered from small radius (R = 0.2) anti-kt jets in Pb +
Pb collisions, and confront them with the recent ATLAS measurements. The Linear Boltzmann Transport (LBT) model is
employed for jet propagation and jet-induced medium excitation in the hot-dense medium. We demonstrate...

My talk is baesed on our work of presenting the first complete next-to-leading-order (NLO) prediction for the single inclusive jet production in pA collisions at forward rapidities within the color glass condensate (CGC) effective theory. Our prediction is fully differential over the final state physical kinematics, which allows the implementation of the full jet clustering algorithm in our...

We study the transverse-momentum-dependent parton distribution functions
(TMDs) up to twist-4 in the MIT bag model. Besides the TMDs defined
from the quark-quark correlator, we have also calculated those defined
via quark-$j$-gluon-quark correlators and four-quark correlators
for the first time. All the T-even and T-odd TMDs are computed to
the $\alpha_{s}^{1}$ level. Furthermore, we...
