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…

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…

First $π K$ atom lifetime and $π K$ scattering length measurements

B. Adeva, L. Afanasyev, Y. Allkofer +65

The results of a search for hydrogen-like atoms consisting of $π^{\mp} K^{\pm}$ mesons are presented. Evidence for $π K$ atom production by 24 GeV/c protons from CERN PS interacting…
