DESCRIPTION:The K+ → π+ν¯ν decay is a golden mode for flavour physic
 s. Its branching ratio is predicted with high precision by the Standard Mo
 del to be less than 10^−10\, and this decay mode is highly sensitive to 
 indirect effects of new physics up to the highest mass scales. The NA62 e
 xperiment at the CERN SPS is designed to study the K+ → π+ν¯ν decay\
 , and provided the world’s most precise investigation of this decay usin
 g 2016-18 data. Building on this success the first results from a signific
 antly improved analysis of new data\, taken in 2021-22 after beam-line and
  detector upgrades\, are presented\, as well as the combination with the 2
 016-18 results.
