MEASUREMENT OF THE ee →ππ2πη CROSS SECTION BELOW √s = 2 GeV
The cross section for the process ee → ππ2πη is measured in the center-of-mass energy region 1.55–2 GeV for integrated luminosity 146 pb collected by the SND detector at the VEPP-2000 ee collider. The obtained cross section is fitted with theVMDmodel with the ρ(1700) and ρ(2150) resonances.
