The NA62 experiment at CERN: status and perspectives

The NA62 experiment at CERN will measure the branching ratio of the K+ → pi+ nu nubar decay with a precision of 10%, collecting about 100 events in two years of run. This paper will review the design of the experiment, the strategy for the measurement and the actual status of the installation. Prospects for the data collection and for the measurement of other rare K+ channels will be presented.
