A sample of 3984 candidates the K+→π+γγ decay, with an estimated background 291±14 events, was collected by NA62 experiment at CERN during 2017–2018. In order to describe observed di-photon mass spectrum, next-to-leading contribution in chiral perturbation theory found be necessary. The decay branching ratio full kinematic range is measured (9.61±0.17)×10−7. first search for production and prompt axion-like particle gluon coupling process K+→π+a, a→γγ also reported.

The NA62 experiment at CERN SPS is designed to study the $K^+\to\pi^+\nu\bar\nu$ decay. After collecting data in 2016, 2017, and 2018, has resumed taking 2021 received approval for operations until onset of LS3. first search lepton number violating decay $K^+\to\pi^0\pi^-\mu^+ e^+$ flavour decays $K^+\to\pi^0\pi^+\mu^+ e^-$ , $K^+\to\pi^0\pi^+\mu^- reported.

The first search for ultra-rare K+ decays into the π+e+e−e+e− final state is reported, using a dataset collected by NA62 experiment at CERN in 2017–2018. An upper limit of 1.4×10−8 90% CL obtained branching ratio K+→π+e+e−e+e− decay, predicted Standard Model to be (7.2±0.7)×10−11. Upper limits are level 10−9 ratios two prompt decay chains involving pair-production hidden-sector mediators: K+→π+aa, a→e+e− and K+→π+S, S→A′A′, A′→e+e−.
The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory is planned to begin in the Fall 2025. LSST survey cadence has been designed via a community-driven process regulated by Cadence Optimization Committee (SCOC), which recommended up 3% observing time carry out Target Opportunity (ToO) observations. Experts from scientific community, personnel, members SCOC were brought together deliver recommendation for implementation ToO program during workshop held March 2024. Four main...
Recent results from searches for rare kaon decays with the NA62 experiment at CERN are reported, together future prospects. A HIKE, to go beyond NA62, has been proposed push physics an unprecedented frontier. The HIKE timescale and expected performance described. Among results, measurement of branching ratios flavour changing neutral current $K^+\rightarrow\pi^+\mu^+\mu^-$ radiative non leptonic $K^+\rightarrow\pi^+\gamma\gamma$ upper limits given lepton flavor number violating...
The K+ -> pi+ nu nubar decay is a golden mode for search of New Physics in the flavour sector. Standard Model prediction its branching ratio less than 10^-10. NA62 experiment at CERN SPS designed to study decay, and provides world's most precise investigation this decay. multi-purpose high-intensity kaon experiment, also carries out broad rare-decay hidden-sector physics programme with dedicated trigger lines.
The NA62 experiment reports the branching ratio measurement $BR(K^+\to\pi^+\nu\bar\nu)$ at 68% CL, based on observation of 20 signal candidates with an expected background 7.0 events from total data sample collected CERN SPS during 2016-2018. This provides evidence for very rare $K^+\to\pi^+\nu\bar\nu$ decay, observed a significance $3.4\sigma$. achieves single event sensitivity $(0.839\pm0.054)\times10^{-11}$, corresponding to 10.0 assuming Standard Model $(8.4\pm1.0)\times10^{-11}$. result...
