Investigation of $K^{+} K^{-}$ pairs in the effective mass region near $2 m_{K}$

B. Adeva, L. Afanasyev, A. Anania +53

The DIRAC experiment at CERN investigated in the reaction $p (24 GeV /c) + Ni$ the particle pairs $K^{+} K^{-}, π^{+} π^{-}$ and $p p ˉ$ with relative momentum $Q$ in the pair s…

First measurement of a long-lived $π^{+} π^{-}$ atom lifetime

B. Adeva, L. Afanasyev, A. Anania +56

The adapted DIRAC experiment at the CERN PS accelerator observed for the first time long-lived hydrogen-like $π^{+} π^{-}$ atoms, produced by protons hitting a beryllium target. A part…

Measurement of the $π K$ atom lifetime and the $π K$ scattering length

DIRAC Collaboration, B. Adeva, L. Afanasyev +62

After having announced the statistically significant observation (5.6~ $σ$ ) of the new exotic $π K$ atom, the DIRAC experiment at the CERN proton synchrotron presents the measurement…

Search for the rare decay $K^{+} \to μ^{+} ν ν ˉ ν$

A. V. Artamonov, B. Bassalleck, B. Bhuyan +57

Evidence of the $K^{+} \to μ^{+} ν ν ˉ ν$ decay was searched for using E949 experimental data with an exposure of $1.70 \times 1 0^{12}$ stopped kaons. The data sample is dominated by the b…

Observation of $π^{-} K^{+}$ and $π^{+} K^{-}$ atoms

DIRAC Collaboration

The observation of hydrogen-like $π K$ atoms, consisting of $π^{-} K^{+}$ or $π^{+} K^{-}$ mesons, is presented. The atoms have been produced by 24 GeV/ $c$ protons from the CERN PS accelera…

Search for heavy neutrinos in $K^{+} \to μ^{+} ν_{H}$ decays

A. V. Artamonov, B. Bassalleck, B. Bhuyan +57

Evidence of a heavy neutrino, $ν_{H}$ , in the $K^{+} \to μ^{+} ν_{H}$ decays was sought using the E949 experimental data with an exposure of $1.70 \times 1 0^{12}$ stopped kaons. With the major…
