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…

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…
