Measurement of the $e^+e^- \to ηπ^+π^-$ cross section with the SND detector at the VEPP-2000 collider (1711.08862v1)
Published 24 Nov 2017 in hep-ex
Abstract: The $e+e- \to \eta\pi+\pi-$ cross section is measured at the SND detector in the $\eta$ decay mode $\eta\to 3\pi0$. The analysis is based on the data sample with an integrated luminosity of 32.7 pb${-1}$ collected at the VEPP-2000 $e+e-$ collider in the center-of-mass energy range $\sqrt{s}=1.075-2.000$ GeV. The data obtained in the $\eta\to 3\pi0$ decay mode are found to be in agreement with the previous SND measurements in the $\eta\to \gamma\gamma$ mode. Therefore the measurements in the two modes are combined.
