Experimental light mesons measurements are important in the study of heavy ion collisions, serving as hard probes of the quark gluon plasma (QGP). The research of light mesons in U + U collisions at 192 GeV allows discriminating the effects of hot matter depending on the geometric characteristics of the colliding heavy nuclei. The nuclear modification factor RAA is sensitive to hot and cold nuclear matter effects present during the event. This paper presents invariant spectra, nuclear modification factors and ratio of invariant spectra of light mesons. These values studying to depend of transverse momentum, numbers of collisions, numbers of participant and centrality.
