Photons as Probes of Deconfinement in Quark-Gluon Plasma : [Abstract] / S.N.Nedelko, A.V.Nikolskii // Физика элементарных частиц и атомного ядра. Письма. – 2023. – Т.20, №5. – P.1296. – URL: http://www1.jinr.ru/Pepan_letters/panl_2023_5/37_Nedelko_ann.pdf.

The specific mechanism of photon production by conversion from gluons gg → γ in the framework of the mean-field approach to the QCD vacuum is discussed. In the confinement phase, the conversion probability of gluons into a photon vanishes due to the random orientation of the statistical ensemble of confining vacuum fields. In contrast, the conditions of the Furry theorem are violated in the deconfinement phase; as a consequence, the conversion probability of gluons is nonzero, and photon distribution has a strong angular anisotropy. Thus, the photon production in the investigated process can act as one of the important probes of transition in quark–gluon plasma to the deconfinement phase.
