TL;DR
This study measures soft photon production in nucleus-nucleus collisions at 3.5 GeV/nucleon, finding an excess yield below 50 MeV that surpasses theoretical predictions and aligns with prior high-energy experiments.
Contribution
First experimental measurement of soft photon yield at this energy, confirming excess production and validating previous high-energy findings.
Findings
Excess soft photon yield observed below 50 MeV.
Results agree with previous high-energy collision experiments.
Spectra exceed theoretical estimations.
Abstract
First results of study of a soft photon yield at Nuclotron (LHEP, JINR) in nucleus-nucleus collisions at 3.5 GeV per nucleon are presented. These photons are registered by an BGO electromagnetic calorimeter built by SVD-2 Collaboration. The obtained spectra confirm the excessive yield in the energy region less than 50 MeV in comparison with theoretical estimations and agree with previous experiments at high-energy interactions.
