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…
