The conversion probability and emission ratio of charged Sigma - hyperons following K/sup -/ meson capture at rest in carbon

A study has been made of K/sup -/ meson interactions at rest in the CERN 1.1 m/sup 3/ heavy liquid bubble chamber filled with a mixture of hydrocarbons. The data are used to determine (i) the internal conversion probability, C( Sigma /sup -/), of Sigma /sup -/ hyperons produced in association with p...

description A study has been made of K/sup -/ meson interactions at rest in the CERN 1.1 m/sup 3/ heavy liquid bubble chamber filled with a mixture of hydrocarbons. The data are used to determine (i) the internal conversion probability, C( Sigma /sup -/), of Sigma /sup -/ hyperons produced in association with pi /sup +/ mesons by K/sup -/ meson interactions in carbon nuclei, (ii) the relative emission frequencies of ( Sigma /sup +/ pi /sup +/) and ( Sigma /sup -/ pi /sup +/) pairs, E( Sigma /sup +/ pi /sup +// Sigma /sup -/ pi /sup +/), and the emission frequency E( Sigma /sup +or-/ pi /sup -or+//K/sup -/), of ( Sigma /sup +or-/ pi /sup -or+/) pairs per K/sup -/ meson absorption in carbon, (iii) the branching fraction, P( Sigma /sup -/ pi /sup +//K /sup -/), for the primary process K/sup -/+p to Sigma /sup -/+ pi /sup +/ in carbon and (iv) the trapping probability, T( Lambda /sup 0/), for Lambda /sup 0/ hyperons produced by Sigma /sup -/ hyperon interactions in carbon nuclei.
