The NA62 Experiment at CERN

Understand

The main physics goal of the NA62 experiment at CERN is to precisely measure the branching ratio of the kaon rare decay $K^+\rightarrow \pi^+ \nu \bar\nu$.

• This decay is strongly suppressed in the Standard Model and its branching ratio is theoretically calculated with high accuracy.
• The NA62 experiment is designed to measure this decay rate with an uncertainty better than 10\%.
• The measurement can be a good probe of new physics phenomena, which can alter the SM decay rate.
