Measurement of the cross section for the e +e - → ωπ 0 → π 0π 0γ process in the energy range of 1.1-1.9 GeV
The cross section for the e +e - → ωπ 0 → π 0π 0γ process has been measured in the energy range of 1.1-1.9 GeV. The measurement has been made with the Spherical Neutral Detector at the VEPP-2000 e +e - collider. The data in the energy range of 1.1-1.4 GeV are in agreement with the earlier measurements with the SND and CMD-2 detectors. The cross section has also been measured above 1.4 GeV. © 2011 Pleiades Publishing, Ltd.
