${{\mathit \Sigma}^{+}}$ MASS

INSPIRE   JSON  (beta) PDGID:

S019M

The fit uses ${{\mathit \Sigma}^{+}}$, ${{\mathit \Sigma}^{0}}$, ${{\mathit \Sigma}^{-}}$, and ${{\mathit \Lambda}}$ mass and mass-difference measurements.

VALUE (MeV) EVTS DOCUMENT ID TECN  COMMENT $\bf{ 1189.37 \pm0.07}$ OUR FIT  Error includes scale factor of 2.2. $\bf{ 1189.37 \pm0.06}$ OUR AVERAGE  Error includes scale factor of 1.8.  See the ideogram below. $1189.33$ $\pm0.04$ 607 1 BOHM 1972 EMUL $1189.16$ $\pm0.12$ HYMAN 1967 HEBC $1189.61$ $\pm0.08$ 4205 SCHMIDT 1965 HBC See note with ${{\mathit \Lambda}}$ mass $1189.48$ $\pm0.22$ 58 2 BHOWMIK 1964 EMUL $1189.38$ $\pm0.15$ 144 2 BARKAS 1963 EMUL 1  BOHM 1972 is updated with our 1973 ${{\mathit K}^{-}}$, ${{\mathit \pi}^{-}}$, and ${{\mathit \pi}^{0}}$ masses (Reviews of Modern Physics 45 S1 (1973)). 2  These masses have been raised 30 keV to take into account a 46 keV increase in the proton mass and a 21 keV decrease in the ${{\mathit \pi}^{0}}$ mass (note added 1967 edition, Reviews of Modern Physics 39 1 (1967)).
