We propose an experimental test of the gravitational interaction with antimatter by measuring the branching fraction of the CP violating decay KL→π+π- in space. We show that at the altitude of the International Space Station, gravitational effects may change the level of CP violation such that a 5σ discrimination may be obtained by collecting the KL produced by the cosmic proton flux within a few years.

Abstract
We propose an experimental test of the gravitational interaction with antimatter by measuring the branching fraction of the CP violating decay KL→π+π- in space. We show that at the altitude of the International Space Station, gravitational effects may change the level of CP violation such that a 5σ discrimination may be obtained by collecting the KL produced by the cosmic proton flux within a few years.File in questo prodotto:
