Abstract

The differential cross sections of light meson production: X = pi (0), eta and omega were measured in (p) over right arrowp --> ppX reaction. A theoretical analysis based on s-channel contributions in 2(+) and 1(-) intermediate states was performed. Narrow peaks were looked for between eta and omega meson masses, and were extracted at 588, 608, 647, 681 and 700 MeV. The evidence for their existence is discussed in accordance with the corresponding number of standard deviations (SD).
