First observation of $\pi^{-}K^+$ and $\pi^{+}K^-$ atoms, their lifetime measurement and $\pi K$ scattering lengths evaluation

The Low Energy QCD allows to calculate the ππ and π K scattering lengths with high precision. There are accurate relations between these scattering lengths and π + π − , π − K + , π + K − atoms lifetimes. The experiment on the first observation of π − K + and π + K − atoms is described. The atoms we...
