Electroweak probes
Oral Presentation
The penetrating nature of dileptons makes them suitable probes to explore the properties of the strongly-interacting medium created in relativistic nuclear collisions. This study investigates thermal dilepton production using MUSIC (a Monotone Upstream-centered Scheme for Ion Collisions): a 3+1D hydrodynamic simulation with or without shear viscosity. We utilize dilepton emission rates that...

Electroweak probes
Oral Presentation
Measurements of lepton pair spectra are a crucial tool to map out the evolution of the hot dense matter created in ultra-relativistic heavy ion collisions. At low pair mass, direct photons and low mass vector mesons are the main center of interest. Interpretation of lepton pair production rates in excess of expectations from hadronic decays observed by PHENIX and how the data constrains...

Electroweak probes
Oral Presentation
Di-leptons serve as clean and bulk penetrating probes to study
the properties of the strongly interacting hot and dense medium
created in heavy ion collisions. They are produced in all stages
of the heavy-ion collisions and are not affected by strong
interactions, hence can probe the entire evolution of the
collision. Di-lepton production in the low mass range
($M_{ll}<1.1$ GeV/$c^{2}$)...

We investigate the correlations of photons produced by back scattering of fast partons in quark gluon plasma
with their away‐side jets. Back scattering with photon emission, or jet‐photon conversion,
was originally proposed as a novel source of photons in Phys. Rev. Lett. 90, 132301 (2003).
The unique appeal of this photon source lies in the fact that its photons carry information about b...

Direct photons are an important probe in diagnosing the highly excited state of nuclear matter created in heavy-ion collisions: They allow access to various stages of the collision including the initial state.
The ALICE detector is equipped with two high resolution electromagnetic calorimeters and a central tracking system that make it well suited to study direct photon production at low...
