| Research Abstract |
The main aim of the study is to execute the DIRAC experiment at CERN PS, measure directly the life times ofππand Kπhadronic atoms, and deduce the scattering lengths ofππandπK pairs. A comparison of those values with those calculated with a high precision by the chiral perturbation theory should allow us to make a test of QCD in the non-perturvative region. Also we aim at the extension of the study in order to investigate the excited states ofππand Kπhadronic atoms, and measure the Lamb shifts.
