Measurement of the e+e−→ ηπ+π− cross section with the CMD-3 detector at the VEPP-2000 collider

Abstract The cross section of the process e+e−→ ηπ+π− is measured using the data collected with the CMD-3 detector at the VEPP-2000 collider in the center-of-mass energy range from 1.1 to 2.0 GeV. The decay mode η → γγ is used for η meson reconstruction in the data sample corresponding to an integra...
