چکیده
The cross section of the process e+e− → ηγ has been measured in the 600-1380 MeV c.m. energy range with the CMD-2 detector. The following branching ratios have been determined: B(ρ → ηγ) = (3.28 ± 0.37 ± 0.23) · 10 , B(ω → ηγ) = (5.10 ± 0.72 ± 0.34) · 10 , B(φ → ηγ) = (1.287 ± 0.013 ± 0.063) · 10 . Evidence for the ρ(1450) → ηγ decay has been obtained for the first time.

Study of the Process e + e − → ωπ 0 → π 0 π 0 γ in c.m. Energy Range 920–1380 MeV at CMD-2
The cross section of the process e+e− → ωπ0 → π0π0γ has been measured in the c.m. energy range 920–1380 MeV with the CMD-2 detector. Its energy dependence is well described by the interference of the ρ(770) and ρ(1450) mesons decaying to ωπ0. Upper limits for the cross sections of the direct processes e+e− → π0π0γ, ηπ0γ have been set.

The cross section of the process e+e− → π0π0γ has been measured in the c.m. energy range 600–970 MeV with the CMD-2 detector. The following branching ratios have been determined: B(ρ0 → π0π0γ) = (5.2 −1.3 ± 0.6) × 10−5 and B(ω → π0π0γ) = (6.4 −2.0 ± 0.8) × 10−5. Evidence for the ρ0 → f0(600)γ decay has been obtained: B(ρ0 → f0(600)γ) = (6.0 −2.7 ± 0.9) × 10−5. From a search for the process e+e−...

The e + e ? collider VEPP-2M at Novosibirsk is the only machine covering the energy range 360-1400 MeV. The peak luminosity is 5: 10 30 cm ?2 s ?1 for the resonance region. Two modern detectors-the general purpose magnetic detector CMD-2 and Spherical Neutral Detector (SND) are taking data at the VEPP-2M collider. The integrated luminosity about 10 pb ?1 has been collected by both detectors. La...
