Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target

G. D. Alexeev, M. G. Alexeev, C. Alice +166

The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable $x$ , th…

Measurement of the $K^{+} \to π^{+} γ γ$ decay

The NA62 Collaboration

A sample of 3984 candidates of the $K^{+} \to π^{+} γ γ$ decay, with an estimated background of $291 \pm 14$ events, was collected by the NA62 experiment at CERN during 2017-2018. In order t…

Search for $K^{+}$ decays to a muon and invisible particles

NA62 collaboration

The NA62 experiment at CERN reports searches for $K^{+} \to μ^{+} N$ and $K^{+} \to μ^{+} ν X$ decays, where $N$ and $X$ are massive invisible particles, using the 2016-2018 data set. The $N$ par…

Search for $π^{0}$ decays to invisible particles

NA62 Collaboration

The NA62 experiment at the CERN SPS reports a study of a sample of $4 \times 1 0^{9}$ tagged $π^{0}$ mesons from $K^{+} \to π^{+} π^{0} (γ)$ , searching for the decay of the $π^{0}$ to invisibl…

Search for Axionlike and Scalar Particles with the NA64 Experiment

D. Banerjee, J. Bernhard, V. E. Burtsev +52

We carried out a model-independent search for light scalar (s) and pseudoscalar axionlike (a) particles that couple to two photons by using the high-energy CERN SPS H4 electron bea…
