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…

Angular distribution in s-channel formation of the pentaquark $Θ^{+}$ baryon

DIANA Collaboration, V. V. Barmin, A. E. Asratyan +10

Using the DIANA data on the charge-exchange reaction $K^{+} n \to p K^{0}$ on a bound neutron, in which the s-channel formation of the pentaquark baryon $Θ^{+} (1538)$ has been obse…
