---------- Title: Light nuclei production as a probe of QCD phase diagram ---------- Abstract: Fluctuation signals of phase transitions from quark-gluon plasma (QGP) to hadronic matter can greatly advance our knowledge of the nature of strong interaction. In relativistic heavy-ion collisions, the enhanced density fluctuations due to phase transitions (either first-order or second ... More
---------- Title: Measurement of Open Heavy Flavor Production in Au+Au Collisions at $\sqrt{s_{NN}}$ = 200 GeV in STAR ---------- Abstract: Due to the large mass, heavy quarks are suggested to be an important tool for studying the properties of the Quark Gluon Plasma (QGP) produced in heavy-ion collisions. In this presentation, we will report on the measurements of production of vari ... More
Title: Search for the chiral magnetic effect in relativistic heavy-ion collisions ------------------------------------------------------------------------------------------------------ Speaker: Jie Zhao (赵杰), Purdue University Date: Thursday, Dec. 12, 10:30 am (Beijing time) Download: https://pan.baidu.com/s/1KDPSLBjYd7kmOqKjYndzQg access code: vmgj --------------------------------- ...

---------- Title: Linear response theory and its application in the heavy-ion collisions ---------- Abstract: The linear response theory describe the system reaction against an external perturbation which drives the system away from the equilibrium, and is therefore widely used for studying the relaxation or the instability of a system near equilibrium. I will give an introductio ... More
---------- Title: Recent heavy-flavor results from ATLAS ---------- Speaker: Dr. Qipeng Hu (胡启鹏),  University of Colorado Boulder, US (美国科罗拉多大学博尔德分校) ---------- Date: Thursday, Jan. 16, 2020, 10:30 am (Beijing time) ---------- Abstract:    ---------- In A+A collisions, heavy-flavor (charm and bottom) quarks are ...

---------- Title: From Open Quantum System to Quarkonium Transport inside Quark-Gluon Plasma ---------- Abstract:   ---------- The production of heavy quarkonium in heavy ion collisions has been used as an important probe of the quark-gluon plasma. Transport equations that take into account static plasma screening effect, dissociation and recombination have achieved great ... More
---------- Title: Pre-hydrodynamics and pre-hydrodynamic response ---------- Abstract:   ---------- We propose a new scenario characterizing the transition of the quark-gluon plasma (QGP) produced inheavy-ion collisions from a highly non-equilibrium state at early times toward a fluid described by hydrodynamics at late times. In this scenario, the bulk evolution is gove ... More
---------- Title: Probing the linear polarization of coherent photons in heavy ion collisions ---------- Abstract:   We propose to measure the linear polarization of the external electromagnetic fields of a relativistic heavy ion through azimuthal asymmetries in dilepton production. I will also show that the linearly polarized photons can be used as a powerful probe to study ... More
---------- Title: Spin polarizations in a covariant angular momentum conserved chiral transport model ---------- Abstract:   Using a covariant and total angular momentum conserved chiral transport model, which takes into account the spin-orbit interactions of chiral fermions in their scatterings via the anomalous side jump effect, we study the quark spin polarizations in quark m ... More
---------- Title: Direct photon+jet and h+jet measurement: STAR heavy-ion physics to future forward upgrade ---------- Abstract:   The hot-dense QCD medium, popularly known as Quark-Gluon Plasma (QGP), is believed to be formed in the relativistic heavy-ion collider experiments. A high energetic parton traversing through this state of matter loses energy by radiating gluons due to its ... More
---------- Title: Charm-hadron production in pp and AA collisions ---------- Abstract:   The enhancements of D_s/D^0 and Lambda_c/D^0 ratios in heavy-ioncollisions as recently measured at RHIC and the LHC have posedchallenges for theoretical models. We address these puzzles bydeveloping a theoretically controlled hadronization framework of heavyquarks that conserves 4-momentum and rec ... More
---------- Title:  The Collectivity of Heavy Mesons in pA collisions ---------- Abstract:   Employing a model based on the Color Glass Condensate framework, we systematically study the azimuthal angular correlations between a heavy flavor meson and a light reference particle in proton-nucleus collisions. The obtained second harmonic coefficients (also known as the elliptic flows) for ... More
---------- Title: Strong physics at LHCb: probing nuclear matter effects in small systems ---------- Abstract:   The Standard Model of particle physics has demonstrated its predictive power in the electroweak and Higgs sectors, through the long-anticipated discovery of the Higgs boson and the per-mille-level agreement between direct and indirect determinations of the W-boson mass. How ... More

---------- Title: Importance of non-flow background on the chiral magnetic wave search ---------- Abstract:   An observable sensitive to the chiral magnetic wave (CMW) is the charge asymmetry dependence of the π− and π+ anisotropic flow difference, Δvn(Ach). We show that, due to non-flow correlations, the flow measurements by the Q-cumulant method using all charged particles as r ... More

---------- Title: Quarkonium Measurements in p+p, p+Au and Au+Au Collisions at 200 GeV with the STAR Experiment ---------- Abstract:   Measurements of quarkonium production are an important tool to study the properties of the Quark-Gluon Plasma (QGP) formed in relativistic heavy-ion collisions. Quarkonium suppression due to the color-screening effect was proposed as a direct evidence of the ... More
