Observation of $\pi^- K^+$ and $\pi^+ K^-$ atoms
Experiment DIRAC at CERN PS detects 349 ± 62 pairs from $\pi^-K^+$ and $\pi^+K^-$ atoms and makes observation of exotic atoms consist of pion and kaon. It allows to measure a difference of S-wave pion-kaon scattering length with isospin 1/2 and 3/2: $|a{_0^{1/2}}−a{_0^{3/2}}|$. Values of pion-kaon s...

| description | Experiment DIRAC at CERN PS detects 349 ± 62 pairs from $\pi^-K^+$ and $\pi^+K^-$ atoms and makes observation of exotic atoms consist of pion and kaon. It allows to measure a difference of S-wave pion-kaon scattering length with isospin 1/2 and 3/2: $|a{_0^{1/2}}−a{_0^{3/2}}|$. 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 these predictions for simplest hadronhadron system with s-quark. |
