Measurement of the $\Sigma^{0}$ lifetime

The Coulomb production of Sigma /sup 0/ hyperons on uranium and nickel nuclei has been measured in a beam of Lambda hyperons at the CERN Proton Synchrotron. The results for the Sigma /sup 0/ lifetime, tau = (0.58+or-0.13)*10/sup -19/ sec, and for the Sigma /sup 0/- lambda magnetic transition moment,...

Descripción
Sumario:The Coulomb production of Sigma /sup 0/ hyperons on uranium and nickel nuclei has been measured in a beam of Lambda hyperons at the CERN Proton Synchrotron. The results for the Sigma /sup 0/ lifetime, tau = (0.58+or-0.13)*10/sup -19/ sec, and for the Sigma /sup 0/- lambda magnetic transition moment, mod mu mod =(1.82(+0.25, -0.18)) nuclear magnetons, are in agreement with SU(3) predictions.
