THE MASS OF THE SIGMA-PLUS HYPERON
Technical Report
·
OSTI ID:4161617
The stars produced by mesons (K/sup -/) stopping in nuclear emulsion were investigated to find examples of the decay at rest of SIGMA /sup +/ yields p + pi /sup 0/. Fourteen examples of this decay were obtained. The mean weighted range of the proton, corrected to the range in emulsion of standard density, is 1676.3 plus or minus 7.7 microns. This corresponds to a kinetic energy of 18.85 Mev. The mass of the SIGMA /sup +/ was found to be 1189.41 plus or minus 0.54 Mev. (auth)
