Description

The NA62 experiment aims to measure the very rare kaon decay K+ → π+νnubar at the CERN SPS. The expected branching ratio has been recently estimated within the Standard Model to be (8.22 ± 0.84) x 10-11. From the experimental side, 7 events has been found by E787/949 experiments at BNL providing a measurement of the branching ratio of (1.73+1.15-1.05) x 10-10. The aim of NA62 is to collect ∼100 events in two years of data taking with a 10% background. A description of the setup and the R and D program is presented.
