The DIRAC experiment at CERN
Abstract
Description
The DIRAC experiment at CERN aims to measure the lifetime of the pionium atom ($A_{2π}$), a $π^+π^-$ 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 $|a_0 - a_2|$ with 5% precision.
