Electroweak Probes
Electromagnetic probes are considered as clean messengers from the hot dense medium created in the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC). In this talk, I will review the theoretical developments in the study of electromagnetic radiation in relativistic heavy-ion collisions. The recent progress in the rates for photon and lepton pair production is discussed....

Electroweak Probes
Electroweak bosons processes (W, Z and photon) provide experimental controls over initial geometric and nuclear PDFs (nPDFs). The ATLAS has measured the production of all three bosons in Pb+Pb at 2.76 TeV and the production of Z bosons in p+Pb collisions at 5.02 TeV. Z bosons are measured via both di-electron and di-muon decay channel. W bosons are measured with isolated single leptons and...

Electroweak Probes
Electroweak production is an important benchmark in heavy-ion collisions at the LHC. Electroweak bosons (W and Z) do not participate in strong interaction and their leptonic decays play as an idea tag to probe properties of jets that interact with the medium strongly. They, moreover, constrain nuclear parton distribution functions (nPDFs) in unexplored region of Q^2 - x phase space. They can...

ALICE (A Large Ion Collider Experiment) is designed and optimized to study ultra-relativistic heavy-ion collisions, in which a hot and dense, strongly-interacting medium is created. W bosons are produced in hard scattering processes and interact weakly with the medium formed in heavy-ion collisions. Thus, these electroweak bosons are suitable references for processes which are heavily affected...

Electroweak Probes
We reproduced the observed large v2, v3 of direct photons and predicted a large v2, v3 of thermal dileptons based on EPOS 3, a hadron data constrained (3+1)D viscous hydro model and normal emission rates of photons and dileptons from QGP phase and hadronic gas phase.
Direct photon v2 is in fact a puzzle for our field for quite long time. Why can EPOS3 reproduce the challenging experimental...

Electroweak Probes
Heavy-ion collisions can generate extremely hot/dense medium and extremely strong electromagnetic fields. We discuss some general properties of these fields, including the centrality dependence, collision energy dependence, azimuthal correlations to the matter geometry, etc. Once there appear parity-odd domains in the quark-gluon plasma, the electromagnetic field can induce anomalous...
