Observation of the 'forbidden' double charge exchange reaction pp to Sigma /sup -/ Sigma /sup -/ at 36 GeV/c

Data are presented which firmly establish the existence of the double charge exchange reaction pp to Sigma /sup -/ Sigma /sup -/ at 3.6 GeV /c. The forward cross section was found to be (5.9+or-1.1) mu b and the ratio of the 'forbidden' to 'allowed' forward cross-section is R= si...

Sumario:Data are presented which firmly establish the existence of the double charge exchange reaction pp to Sigma /sup -/ Sigma /sup -/ at 3.6 GeV /c. The forward cross section was found to be (5.9+or-1.1) mu b and the ratio of the 'forbidden' to 'allowed' forward cross-section is R= sigma ( Sigma /sup -/ Sigma /sup -/)/ sigma ( Sigma /sup +/ Sigma /sup +/)=0.09+or-0.02.
