Description
In this work we discuss the interest of measuring the ratio of pp annihilation into kaon and pion pairs near the threshold region, where the S state dominates. It is shown that a good agreement with existing data on the ratio of the yields of charged kaon to pion pairs is obtained taking into account not only quark rearrangement in the incident hadrons, but also vacuum excitations.
