High precision mass measurements in Ψ and ϒ families revisited
High precision mass measurements in Ψ and ϒ 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/ Ψ(1 S) a...

Summary: | High precision mass measurements in
Ψ and
ϒ 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/
Ψ(1
S) and
Ψ(2
S) mass measurements. |
