First observation of the K+ → π+νν decay with the NA62 experiment

Key Points

• The research aims to observe the K+ decay into π+ and neutrinos, which has significant implications for understanding fundamental particles.
• Conducted the NA62 experiment at CERN over multiple years (2016-2022).
• Collected data from three distinct years before resuming operations in 2021.
• Combined data across years to achieve the first observation of the decay.
• Successfully observed the K+ decay into π+ and neutrinos.
• Data was collected up to 2022, indicating ongoing experimental progress.
• Operations approved to continue until Long Shutdown 3 in 2026.
