Measurement of the $e^{+}{e}^{-}\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}\ddot{I}{€}^0$ cross section in the energy region from 0.56 to 1.1 GeV with the SND detector

SND Collaboration, M. N. Achasov, A. E. Alizzi +44

The precise measurement of the $e^{+}{e}^{-}\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}\ddot{I}{€}^0$ cross section is performed in the center-of-mass energy range $E=560$--1100 MeV using a data sample of 66 pb${}^{-1}$ collect…
