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…

Determination of $π π$ scattering lengths from measurement of $π^{+} π^{-}$ atom lifetime

B. Adeva, L. Afanasyev, M. Benayoun +92

The DIRAC experiment at CERN has achieved a sizeable production of $π^{+} π^{-}$ atoms and has significantly improved the precision on its lifetime determination. From a sample of 21227…
