The transverse momentum (p t ) dependence, the centrality dependence, and the rapidity dependence of the elliptic flow of thermal photons in Au + Au collisions at √S NN = 200 GeV are predicted on the basis of a three-dimensional ideal hydrodynamic description of the hot and dense matter. The elliptic flow parameter ν 2 , i.e., the second Fourier coefficient of azimuthal distribution, of thermal photons first increases with p t and then decreases for p t > 2 GeV/c, because of the weak transverse…

Pseudo-critical enhancement of thermal photons in relativistic heavy-ion collisions?
Abstract We compute the spectra and elliptic flow of thermal photons emitted in ultrarelativistic heavy-ion collisions (URHICs) at RHIC and LHC. The thermal emission rates are taken from complete
Dilepton Spectroscopy of QCD Matter at Collider Energies
Low-mass dilepton spectra as measured in high-energy heavy-ion collisions are a unique tool to obtain spectroscopic information about the strongly interacting medium produced in these reactions.
Thermal photon emission from the πρω system
Abstract We investigate thermal photon emission rates in hot hadronic matter from a system consisting of π , ρ , and ω mesons. The rates are calculated using both relativistic kinetic theory with
Soft Photons from transport and hydrodynamics at FAIR energies
Direct photon spectra from uranium-uranium collisions at FAIR energies (Elab = 35 AGeV) are calculated within the hadronic Ultra-relativistic Quantum Molecular Dynamics transport model. In this
Direct photons at low transverse momentum: a signal for quark-gluon plasma in pp collisions at LHC.
TLDR
It is shown that thermal photon yields increase quadratically with the charged particle multiplicity, which gives an enhanced weight to high multiplicity events, and leads to an important photon production even in minimum-bias events, where the thermal photons largely dominate over the prompt ones at transverse momentum values smaller than 10  GeV/c.
Thermal Radiation Mapping the Space–Time Evolution
Abstract Over the past decade heavy ion experiments at RHIC and now also at LHC uncovered many properties of quark matter produced in collisions of nuclei. Generally, the data is consistent with the
Medium-induced optical effects for prompt photons
Electromagnetic aspects of a QCD matter have been a hot topic in recent years. High-energy heavy-ion experiments revealed that flow harmonics of direct photons are not explained by most hydrodynamic
A tale of tails: Photon rates and flow in ultra-relativistic heavy ion collisions
5 Abstract We consider the possibility that quark and gluon distributions in the medium created in high energy heavy ion collisions may be modied by a power law tail at energies much higher than the
