Photons radiated in heavy-ion collisions are a penetrating probe, and as such can play an important role in the determination of the quark-gluon plasma (QGP) transport coefficients. In the first part of the talk we will present a calculation of the bulk viscous correction to photon production through two-to-two scattering, complementing a previous study involving the shear viscosity [1]. The...

We investigate photon production in the non-equilibrium partonic transport approach BAMPS (Boltzmann Approach to Multi-Parton Scatterings). BAMPS serves as a microscopic tool to study expanding fireballs, employing a stochastic method to solve the relativistic 3+1d Boltzmann equation for quarks, gluons, photons and dileptons. The algorithm is able to closely reproduce the leading order photon...

We investigate the thermal-photon emission from strongly coupled gauge theories at finite temperature via the bottom-up models in holographic QCD in the deconfined phase. Particularly, we apply a model encoding flavor degrees of freedom in the Veneziano limit of a large number of colors $N_c$ and flavors $N_f$ but fixed $x=N_f=N_c$ (VQCD). In this model, the normalization and gauge-field...

Low mass dielectrons are important probes of the hot and dense QCD medium created in heavy-ion collisions, since the production of low mass dielectrons is sensitive to
the thermodynamical properties of the medium and chiral symmetry restoration in the medium.The ALICE experiment at the LHC has measured low mass dielectrons in pp collisions at $\sqrt{s}$ = 7 TeV and p-Pb collisions at...

Lepton pairs are considered as ideal probe to access the microscopic properties of strongly-interacting matter under extreme conditions of temperature and density. The spectral distribution of lepton pairs in the region below the low mass vector mesons is characterized by an excess radiation above contributions from late meson decays (cocktail). It is theoretically well understood as a thermal...
