Using pp{r_arrow}p+ all charged particles at 800 GeV/c and 27.5 GeV/c incident protons at Fermilah and Brookhaven, respectively, the mass of the {Sigma}{sup 0} hyperon has been measured with an uncertainty of 7 times smaller than the best previous result. This result, M{sub {Sigma}{sup 0}}=1192.65{plus_minus}0.020{plus_minus}0.014 MeV/c{sup 2} is based on 16 times the statistics of previous results. {copyright} {ital 1998 American Institute of Physics.}
