The collective behavior of hadronic particles has been observed in high multiplicity proton-lead collisions at the Large Hadron Collider, as well as in deuteron-gold collisions at the Relativistic Heavy-Ion Collider. In this work we present the first calculation, in the hydrodynamic framework, of thermal photon radiation from such small collision systems. Owing to their compact size, these systems can reach temperatures comparable to those in central nucleus-nucleus collisions. The thermal… 
Collectivity and electromagnetic radiation in small systems
Collective behaviour has been observed in hadronic measurements of high multiplicity proton+lead collisions at the Large Hadron Collider (LHC), as well as in (proton, deuteron, helium-3)+gold
Photons from thermalizing matter in heavy ion collisions
Abstract We investigate the production of direct photons in heavy ion collisions within the modified bottom–up thermalization scenario, which we show to be related to the thermalizing Glasma
Recent developments in the theory of electromagnetic probes in relativistic heavy-ion collisions
The theoretical developments in the study of electromagnetic radiation in relativistic heavy-ion collisions are reviewed. The recent progress in the rates for photon and lepton pair production is
Direct photon production and jet energy-loss in small systems
Two types of penetrating probes, direct photon and QCD jets, are investigated in the background of a small and rapidly expanding droplet of quark-gluon plasma. The additional thermal electromagnetic
Holographic photon production in heavy ion collisions
A bstractThe thermal-photon emission from strongly coupled gauge theories at finite temperature is calculated using holographic models for QCD in the Veneziano limit (V-QCD). The emission rates are

Recent developments aimed at understanding whether, and if so how, systems that produce relatively few particles and are only one to a few times the size of a proton, can behave like fluids are described.
Electromagnetic radiation and collectivity in small quark–gluon droplets
Abstract We study the multiplicity and rapidity dependence of thermal and prompt photon production in p+Pb collisions at 5.02 TeV, using a (3+1)D viscous hydrodynamic framework. Direct photon
Direct-Photon Spectra and Anisotropic Flow in Heavy Ion Collisions from Holography
The thermal-photon emission from strongly coupled gauge theories at finite temperature is calculated by using holographic models for QCD in the Veneziano limit (V-QCD). These emission rates are then
Probing gluon saturation with next-to-leading order photon production at central rapidities in proton-nucleus collisions
A bstractWe compute the cross section for photons emitted from sea quarks in proton-nucleus collisions at collider energies. The computation is performed within the dilute-dense kinematics of the
Thermal and prompt photons at RHIC and the LHC
Abstract Thermal and prompt photon production in heavy ion collisions is evaluated and compared with measurements from both RHIC and the LHC. An event-by-event hydrodynamical model of heavy ion
