Abstract
© 2019 authors. Published by the American Physical Society. The PHENIX collaboration presents first measurements of low-momentum (0.45 GeV/c), but when results from different collision energies are compared, an additional sNN-dependent multiplicative factor is needed to describe the integrated-direct-photon yield.
