The K+ to pi+ nu nubar experiment at CERN
  The NA62 experiment, proposed to measure the very rare decay K+ to pi+ nu nubar at the CERN SPS with 10% accuracy, aims to collect about 80 events in two years of data taking, keeping background contamination lower than 10%. This paper describes the status of the project and the perspectives of the experiment.
