First $nK$ atom lifetime measurement and recent results from the DIRAC experiment
/ Zhabitsky, Mikhail (Dubna, JINR)
/DIRAC Collaboration
We report evidence for $\pi K$ atoms production, using 24 GeV/c proton beam from CERN PS interacting with a thin Ni target. We have identified $(178 \pm 49) \pi K$ pairs, which were produced in a bound state - $\pi K$ atom, which was subsequently broken-up (ionized) in the Ni target. [...]

First observation of $\pi^{-}K^+$ and $\pi^{+}K^-$ atoms, their lifetime measurement and $\pi K$ scattering lengths evaluation
/ Afanasyev, Leonid (Dubna, JINR)
/DIRAC Collaboration
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 investigation of $K^+\pi^−, \pi^+K^−$ and $\pi^+\pi^−$ atoms
/ Yazkov, Valeriy (SINP, Moscow)
Theory, using Low Energy QCD, predicts with high precision the pion-pion and pion-kaon scattering lengths. There is accurate relation between $K^+\pi^−$ and $\pi^+K^-$ atoms lifetime and pion-kaon S-wave scattering lengths with isospin 1/2 and 3/2. [...]

Investigation of $\pi^+ \pi^-$ and $pi$K atoms at DIRAC
/ Yazkov, Valeriy (SINP, Moscow)
/DIRAC Collaboration
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..

Evidence for $\pi$K atoms with DIRAC
/ Benelli, A (CERN ; Zurich U.)
/DIRAC-II Collaboration
Electromagnetically bound $π^{\pm}K^{\mp}$-pairs ($πK$-atoms) have been observed by the DIRAC-II experiment at the CERN-PS. The $πK$-atoms were produced by the 24 GeV/c proton beam impinging on a thin Pt-target. [...]

The C$_4$F$_{10}$ Cherenkov detector for DIRAC-II
/ Horikawa, S (Zurich U.) ; Allkofer, Y (Zurich U.) ; Amsler, C (Zurich U.) ; Brekhovskikh, V (Serpukhov, IHEP) ; Kuptsov, A (Dubna, JINR) ; Pentia, M (Bucharest, IFIN-HH) ; Ullaland, O (CERN) ; Zhabitsky, M (Dubna, JINR)
/DIRAC Collaboration
A new threshold Cherenkov detector using C$_4$F$_{10}$ gas radiator was built and put into operation in the DIRAC-II experiment at CERN. Running on the C$_4$F$_{10}$ at room temperature and atmospheric pressure, the detector discriminates between pions and kaons in the momentum range of 4–8GeV/$c$. [...]
