Production of π0 and η mesons in U+U collisions at sqrt(s)_NN=192 GeV
The PHENIX experiment at the Relativistic Heavy Ion Collider measured π0 and η mesons at midrapidity in U+U collisions at sNN−−−√=192 GeV in a wide transverse momentum range. Measurements were performed in the π0(η)→γγ decay modes. A strong suppression of π0 and η meson production at high transverse momentum was observed in central U+U collisions relative to binary scaled p+p results. Yields of π0 and η mesons measured in U+U collisions show similar suppression pattern to the ones measured in Au+Au collisions at sNN−−−√=200 GeV for similar numbers of participant nucleons. The η/π0 ratios do not show dependence on centrality or transverse momentum, and are consistent with previously measured values in hadron-hadron, hadron- nucleus, nucleus-nucleus, and e+e− collisions.
