Investigation of $\pi^+ \pi^-$ and $pi$K atoms at DIRAC
Measurement of $π^+π^−$ and $πK$ atom lifetimes allows to check prediction of Chiral Perturbation Theory for pion-pion scattering lengths with isospin 0 and 2, and pion-kaon scattering lengths with isospin 1/2 and 3/2. Current status of DIRAC experiment, expected results and proposal for future inve...

| Sumario: | Measurement of $π^+π^−$ and $πK$ atom lifetimes allows to check prediction of Chiral Perturbation Theory for pion-pion scattering lengths with isospin 0 and 2, and pion-kaon scattering lengths with isospin 1/2 and 3/2. Current status of DIRAC experiment, expected results and proposal for future investigations are presented. |
