Measuring the $${{e}^{ + }}{{e}^{ - }} \to {{\pi }^{ + }}{{\pi }^{ - }}2{{\pi }^{0}}\eta $$ Cross Section with the SND Detector
The $${{e}^{ + }}{{e}^{ - }} \to {{\pi }^{ + }}{{\pi }^{ - }}2{{\pi }^{0}}\eta $$ process was studied by using the data collected with the SND detector at the VEPP-2000 $${{e}^{ + }}{{e}^{ - }}$$ -collider in 2011, 2012, and 2019–2021. The cross section of this process was measured in the center-of-mass energy region from 1.55 to 2 GeV. The cross section was fitted well by the vector dominance model (VDM) with the $$\rho (1700)$$ and $$\rho (2150)$$ resonances. Comparison with the only previous measurement at the BABAR detector was performed.
