NA62 results on Dark Sector searches
/ NA62 Collaboration
NA62 is a precision physics experiment studying charged kaons and their decayproducts with an unprecedented accuracy (measurement of the K + → π + ννbranching ratio of the order of 10 −11), allowing indirect probes of new physicsscales up to O(100) TeV. NA62 experiment also searches directly for weaklyinteracting particles of up to O(100) MeV masses in kaon decays and up to O(1)GeV masses when running in the beam dump mode. [...]

SEARCH FOR AN INVISIBLE VECTOR BOSON FROM $\pi^{0}$ DECAYS AT NA62
/ NA62 Collaboration
The high-intensity setup, trigger system flexibility and detector performance make the NA62 experiment at CERN particularly suitable to perform direct searches for long-lived hidden-sector particles, such as dark photons, dark scalars, axion-like particles, and heavy neutral leptons, using kaon and pion decays as well as operating the experiment in dump mode. Results from NA62 will be presented on a search for $π^0$ decays to one photon and an invisible massive dark photon. [...]

$K^+ → π^+ ν\overline{ν}$: first NA62 results
/ NA62 Collaboration
The decay $K^+ → π^+ ν\overline{ν}$ with a very precisely predicted branching ratio of less than 10$^{−10}$ is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the $K^+ → π^+ ν\overline{ν}$ with a decay-in-flight technique, novel for this channel. [...]

/NA62
In this paper we present new results on upper limits for the search of Heavy Neutral Leptons (HNL) with data collected by NA48/2 (2003-2004), NA62-RK (2007) and NA62 (2015) CERN experiments. The data collected with different trigger configuration allow to search for both long and short living heavy neutrinos in the mass range below the kaon mass. [...]

The Gigatracker (GTK) is a hybrid silicon pixel detector developed for NA62, the experiment aimed at studying ultra-rare kaon decays at the CERN SPS. Three GTK stations will provide precise momentum and angular measurements on every track of the high intensity NA62 hadron beam with a time-tagging resolution of 150 ps. [...]

/CALICE
We investigate the three dimensional substructure of hadronic showers in the CALICE scintillator-steel hadronic calorimeter. The high granularity of the detector is used to find track segments of minimum ionising particles within hadronic showers, providing sensitivity to the spatial structure and the details of secondary particle production in hadronic cascades.
