A peak in the η ω mass spectrum from diffractive photoproduction

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The η ω mass spectrum resulting from diffractive photoproduction, by photons of 25–50 GeV, shows a peak at a mass of 1.61±0.04 GeV and width of 0.23±0.08 GeV. Comparison with the corresponding η ρ0 mass spectrum suggests that a resonance interpretation is favoured.
