Measurement of the $e^{+}{e}^{-}\to {\pi }^0\gamma$ cross section in the energy range 1.075--2 GeV at SND

Abstract

The process $e^{+}{e}^{-}\to {\pi }^0\gamma$ is studied with the SND detector at the VEPP-2000 $e^{+}{e}^{-}$ collider. Basing on data with an integrated luminosity of 41 pb${}^{-1}$ recorded in 2010-2012 we measure the $e^{+}{e}^{-}\to {\pi }^0\gamma$ cross section in the center-of-mass energy range from 1.075 up to 2 GeV. In the range 1.4-2.0 GeV the process $e^{+}{e}^{-}\to {\pi }^0\gamma$ is studied for the first time.
