Direct photon production at low transverse momentum in proton-proton collisions at $\sqrt{s}$ = 13 TeV / Murakami, Hikari
Direct photons are unique probes to study quark-gluon plasma (QGP) created in ultra-relativistic heavy-ion collisions, as they are emitted from the whole stages of the space-time evolution with negligible final state interaction [...]
