NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like branching fraction K+ → π+ ν decay, have potential bring significant insights into new physics processes when comparison made with precise theoretical predictions. For this purpose, innovative techniques been developed, in particular, domain low-mass tracking devices. Detector construction spanned several years from 2009 2014. The collaboration started detector...
A search for heavy neutral lepton production in $K^+$ decays using a data sample collected with minimum bias trigger by the NA62 experiment at CERN 2015 is reported. Upper limits $10^{-7}$ to $10^{-6}$ level are established on elements of extended neutrino mixing matrix $|U_{\ell 4}|^2$ ($\ell=e,\mu$) mass range $170-448~{\rm MeV}/c^2$. This improves results from previous searches decays, setting more stringent and extending range.
The NA62 experiment at CERN SPS is designed to study the $K^+\to\pi^+\nu\bar\nu$ decay.

This document reviews the physics program of KLOE-2 detector at DA$\Phi$NE upgraded in energy and provides a simple solution to run collider above $\phi$-peak (up 2, possibly 2.5 GeV). It is shown how precise measurement multihadronic cross section region up 2 (possibly 2.5) GeV would have major impact on tests Standard Model through determination anomalous magnetic moment muon effective fine-structure constant $M_Z$ scale.

The first search for ultra-rare $K^+$ decays into the $\pi^+e^+e^-e^+e^-$ final state is reported, using a dataset collected by NA62 experiment at CERN in 2017-2018. An upper limit of $1.4\times 10^{-8}$ 90% CL obtained branching ratio $K^+\to\pi^+e^+e^-e^+e^-$ decay, predicted Standard Model to be $(7.2\pm0.7)\times 10^{-11}$. Upper limits are level $10^{-9}$ ratios two prompt decay chains involving pair-production hidden-sector mediators: $K^+\to\pi^+aa$, $a\to e^+e^-$ and $K^+\to\pi^+S$,...
The NA62 experiment [1] will measure the BR(K+→π+ν) to within about 10%. To reject dominant background from final state photons, large-angle vetoes (LAVs) must detect particles with better than 1 ns time resolution and 10% energy over a very large range. A low threshold, dynamic range, Time-over-threshold based solution has been developed for LAV front end electronics. Our custom 32 channel 9U board uses pair of threshold discriminators each produce LVDS logic signals. achieved obtained in...
