Original abstract
The NA62 experiment at CERN is designed to study the $ K^+\rightarrow\pi^+\nu\bar\nu$ decay. After collecting data in 2016, 2017, and 2018, the experiment resumed data taking in 2021 and has received approval for operations until the start of Long Shutdown 3 in 2026. The first observation of the $ K^+\rightarrow\pi^+\nu\bar\nu$ decay achieved combining the data collected in 2016-2022 is reported.
