Study of the process e+e- →ηγ in the center-of-mass energy range 1.07-2.00 GeV STUDY of the PROCESS e+e- →ηγ ... M.N. ACHASOV et al.
The e+e-→ηγ cross section has been measured in the center-of-mass energy range 1.07-2.00 GeV using the decay mode η→3π0, π0→γγ. The analysis is based on 36pb-1 of integrated luminosity collected with the SND detector at the VEPP-2000 e+e- collider. The measured cross section of about 40 pb at 1.5 GeV is explained by decays of the ρ(1450) and φ(1680) resonances. © 2014 American Physical Society.
