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.

A search for the $K^+\to\mu^-\nu e^+e^+$ decay, forbidden within Standard Model by either lepton number or flavour conservation depending on of emitted neutrino, has been performed using dataset collected NA62 experiment at CERN in 2016--2018. An upper limit $8.1\times 10^{-11}$ is obtained decay branching fraction 90% CL, improving a factor 250 over previous search.
Quantum Sensing is a rapidly expanding research field that finds one of its applications in Fundamental Physics, as the search for Dark Matter. Devices based on superconducting qubits have already been successfully applied detecting few-GHz single photons via Non-Demolition measurement (QND). This technique allows us to perform repeatable measurements, bringing remarkable sensitivity improvements and dark count rate suppression experiments high-precision microwave photon detection, such...

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−.
Abstract The NA62 experiment at CERN utilises a differential Cherenkov counter with achromatic ring focus (CEDAR) for tagging kaons within an unseparated monochromatic beam of charged hadrons. CEDAR-H detector was developed to minimise the amount material in path by using hydrogen gas as radiator medium. shown satisfy kaon requirements test-beam before installation and commissioning experiment. performance measured data collected 2023.

A measurement of the branching ratio rare leptonic kaon decay $K^\pm \rightarrow \mu^\pm \nu_{\mu} e^+ e^- $ is presented using data collected by NA48/2 experiment in 2003 and 2004. The performed region $M_{ee} > 140$~MeV/c$^2$. In this particular low energy QCD contributions become important can be calculated framework Chiral Perturbation Theory (ChPT).
