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…

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…

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…

Evidence for $π K$ -atoms with DIRAC

B. Adeva, L. Afanasyev, Y. Allkofer +77

We present evidence for the first observation of electromagnetically bound $π^{\pm} K^{\mp}$ -pairs ( $π K$ -atoms) with the DIRAC experiment at the CERN-PS. The $π K$ -atoms are produced by…
