A π^– is sent onto a target producing neutral K-mesons and Λ hyperons. Consider the component of the resulting K beam with momentum p = 10 GeV. What is the ratio between K_S and K_L at the production point? What is it at l = 10 m from the production point? Determine the fraction of decays into 2π that would be observed in the absence of CP violation.
