The DIRAC experiment at CERN

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

The DIRAC experiment at CERN aims to measure the lifetime of the pionium atom (A2πA_{2\pi}), a π+π\pi^+\pi^- bound state with an accuracy of 10%. The experimental setup consists of a high precision magnetic double arm spectrometer, located at the high intensity proton beam of the CERN Proton Synchrotron. This measurement will provide - in a model independent way - the S-wave pion scattering length difference a0a2|a_0 - a_2| with 5% precision.
