CP Violation study in the process e+e- yields J/PSI yields λ λ- yields ρ ρ- π+π- at the τ c F

The reasons for the search of CP violation in hyperon decays are briefly described reviewing the observables experimentally used both in p anti p and in e+e- machines. The expected rates of lambda anti lambda events produced in the J/PSI resonance at the tau c F are presented, showing the possibility of reaching the level of sensitivity at which CP violation effects may occur, according to the STANDARD MODEL. Some considerations for the design of the tau c F accelerator and detector are presented. (author)
