Abstract: (Elsevier)

The process e + e − → π + π − π + π − π 0 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.

electron positron: colliding beams
electron positron: annihilation
pi: multiple production
eta: intermediate state
omega(783): intermediate state
mass spectrum: (pi+ pi- pi0)
omega(1600): electron p
rho(1450): electron p
channel cross section: energy dependence
