Pion-pion scattering lengths from $\pi^{+}\pi^{-}$ atom with the DIRAC experiment
The DIRAC experiment at CERN is presently measuring the lifetime of the pionium atom, a bound state of a pi /sup +/ and pi /sup -/ meson. The isospin 0 and 2 scattering length difference will be determined unambiguously once the value of the lifetime is known. In what follows we describe the present...

| description | The DIRAC experiment at CERN is presently measuring the lifetime of the pionium atom, a bound state of a pi /sup +/ and pi /sup -/ meson. The isospin 0 and 2 scattering length difference will be determined unambiguously once the value of the lifetime is known. In what follows we describe the present status of the experiment, the experimental goals and the first results. (11 refs). |
