High Precision Mass Measurements in $\hat{I}¨$ and $\hat{I}\yen$ Families Revisited

Abstract

High precision mass measurements in $\hat{I}¨$ and $\hat{I}\yen$ families performed in 1980-1984 at the VEPP-4 collider with OLYA and MD-1 detectors are revisited. The corrections for the new value of the electron mass are presented. The effect of the updated radiative corrections has been calculated for the $J/\hat{I}¨(1S)$ and $\hat{I}¨(2S)$ mass measurements.
