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…

First measurement of the $π^{+} π^{-}$ atom lifetime

The DIRAC collaboration

The goal of the DIRAC experiment at CERN (PS212) is to measure the $π^{+} π^{-}$ atom lifetime with 10% precision. Such a measurement would yield a precision of 5% on the value of the $…
