Beschreibung
Experiment DIRAC at CERN PS detects 349+-62 pairs from K+pi- and pi+K-
atoms and make observation of exotic atoms consist of pion and kaons.
It allows to measure a difference of S-wave pion-kaon scattering length
with isospin 1/2 and 3/2: |a1/2 - a3/2|. Values of pion-kaon scattering
lengths are predicted in a frame of ChPT and LQCD. Therefore investigation of pi-K+ and pi+K- atoms gives possibility to check this predictions for simplest hadron-hadron system with s-quark.
