Study of the process e+e- → π+π-π+π-π0 with the CMD-2 detector
The process e+e- → π+π-π+π-π0 has been studied in the center of mass energy range 1280 - 1380 MeV using 3.0 pb-1 of data collected with the CMD-2 detector in Novosibirsk. Analysis shows that the cross section of the five pion production is dominated by the contributions of the ηπ+π- and ωπ+π- intermediate states. (C) 2000 Published by Elsevier Science B.V.
