Observation of Structures at ~ 17 and ~ 38 MeV/c*2 in the *g*g Invariant Mass Spectrum in dCu Collisions at a Momentum of 3.8 GeV/c per Nucleon : XXV International Baldin Seminar on High Energy Physics Problems «Relativistic Nuclear Physics and Quantum Chromodynamics», Dubna, September 18–23, 2023 : Materials / Kh.U.Abraamyan, M.A.Kozhin, S.G.Reznikov, A.S.Sorin, [a.o.] // Физика элементарных частиц и атомного ядра. – 2024. – Т. 55, № 4. – P. 1016. – URL: http://www1.jinr.ru/Pepan/v-55-4/34_Abramyan_ann.pdf.

The results of an analysis of the invariant mass spectra of photon pairs produced in dCu interactions at a momentum of 3.83 GeV/c per nucleon are presented. Signals in the form of enhanced structures at invariant masses of ∼ 17 and ∼ 38 MeV/c2 are observed. The results of testing of the observed signals, including the results of the Monte Carlo simulation, are presented. The test results support the conclusion that the observed signals are the consequence of detection of the particles with masses of ∼ 17 and ∼ 38 MeV/c2 decaying into a pair of photons.
