First $nK$ atom lifetime measurement and recent results from the DIRAC experiment
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. Our analysis yi...
