The coherent photon-nucleus and photon-photon interactions has been studied in detail to probe the gluon distribution in nucleus and to test QED via relativistic heavy-ion collisions. These kind of interactions are traditionally thought to be only exist in ultra-peripheral collisions (UPC), where there is no hadronic interactions. Recently, significant excess of $J/\psi$ yield and dielectron...

In this talk, measurements of RAA and v2 of open heavy-flavour hadrons via semi-leptonic decays to electrons at mid-rapidity and muons at forward rapidity in Pb-Pb collisions at LHC energies will be discussed. The progresses on the analysis of the production and anisotropy of electrons from beauty-hadron decays will be also discussed. In addition the RAA of heavy- flavour hadron decay leptons...

Heavy quarks (charm and beauty) are a powerful probe of the Quark-Gluon Plasma (QGP) formed in high-energy heavy-ion collisions. They are produced in hard scattering processes on a timescale shorter than the QGP formation time and experience the whole system evolution. The measurement of the nuclear modification factor ($R_{\rm AA}$) of open heavy flavours can provide important information...

Heavy Flavor
Production of open heavy flavor in pPb collisions provides insight on the cold nuclear matter effects, and acts as a crucial reference measurement to AA collisions in order to disentangle cold nuclear matter effects from the QGP-related effects. The LHCb experiment has measured the production cross section of open charm and beauty hadrons in proton-lead collisions in the forward rapidity...

With our coupled jet-fluid model [1, 2, 3], we study the nuclear modifications of full jets and jet structures for single inclusive jet, dijet and gamma-jet events in Pb+Pb collisions at both 2.76 TeV and 5.02 TeV. The evolution of full jet shower is studied via a set of coupled transport equations including the effects of collisional energy loss, transverse momentum broadening and...

A jet is a spray of collimated hadrons originated in the fragmentation of an energetic parton. The cross section measurement provides a good test for pQCD calculations, and jet production in pp collisions constitutes a reference for jet quenching study in nucleus-nucleus collisions. In addition, the measurements in different multiplicity intervals will provide insights to understand ...

Hard scattered partons lose their energy when propagating through the hot dense medium created in relativistic heavy ion collision. Jets are excellent probes to study parton energy loss mechanisms. Experimentally high transverse momentum ($p_T$) trigger particles are taken as proxies of jets. Di-hadron correlation measurements in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV will be presented in...

We study the medium-induced gluon emission process experienced by a hard jet parton propagating through dense nuclear matter in the framework of deep inelastic scattering off a large nucleus.
We work **beyond collinear rescattering expansion and soft gluon emission limit**, and derive **a closed formula for medium-induced single gluon emission from a heavy or light quark jet** interacting...

We will present new, exact, finite solutions of relativistic hydrodynamics for
longitudinally expanding fireballs for arbitrary constant value of the speed of
sound (CKCJ). These new solutions generalize earlier, longitudinally finite, exact
solutions, from an unrealistic to a reasonable equation of state, characterized
by a temperature independent (average) value of the speed of...

We perform a systematic study on the decorrelation of anisotropic flows along the pseudorapidity in relativistic heavy-ion collisions at the LHC and RHIC energies.The dynamical evolution of the QGP fireball is simulated via the CLVisc (3+1)D hydrodynamics model, with the fully fluctuating initial condition from AMPT model.
Detailed analysis is performed on the longitudinal decorrelations of...

We apply principal component analysis(PCA) to simulated data of relativistic heavy-ion collisions. Unlike traditional Fourier methods, we apply PCA directly to single particle distribution. Interesting patterns are identified by PCA as eigenmodes, from which we define new flow observables $v_n^{'}$ compared to traditional ones $v_n$. The eigenmodes are very much like traditional Fourier bases,...

Within the framework of the coalescence model based on the phase-space distributions of protons and neutrons
generated from the {{\tt iEBE-VISHNU}} hybrid model with {{\tt AMPT}} initial conditions, we study the spectra and elliptic flow of deuterons and helium-3 in relativistic heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and the Larger Hadron Collider (LHC). Results...

The Large Hadron Collider (LHC) at the European Organization for Nuclear Research(CERN) can provide a good experimental condition to study the production of light (anti) nuclei and to understand the underlying physical mechanisms for collision physics.The centrality dependence of light (anti)nuclei and (anti)hypertriton production in Pb-Pb collisions at LHC energy are investigated using the...
