摘要：The P326 proposal for an experiment to measure the branching ratio of the very rare kaon decay
K+ !p+nn¯ at the CERN SPS is described. The proposed experiment aims to collect about 80
K+ !p+nn¯ events with a 10% of background in two years of data taking. The status of the
project, the R&D and the future perspectives for the experiment are discussed.
