Abstract
The cross section of the process e+eââÏ+ÏâÏ0η has been measured using a data sample of 21.8pbâ1 collected with the CMD-3 detector at the VEPP-2000 e+eâ collider. 2769±95 signal events have been selected in the center-of-mass energy range 1394-2005 MeV. The production dynamics is dominated by the Ï(782)η and Ï(1020)η intermediate states in the lower energy range, and by the a0(980)Ï(770) intermediate state at higher energies.
