Description
| - The results of a search for hydrogen-like atoms consisting of Pi-/+K± mesons are presented. Evidence for PiK atom production by 24 GeV/c protons from CERN PS interacting with a nickel target has been seen in terms of characteristic πK pairs from their breakup in the same target (178±49) and from Coulomb final state interaction (653±42). Using these results the analysis yields a first value for the πK atom lifetime of τ=(2.5+3.0-1.8) fs and a first model-independent measurement of the S-wave isospin-odd πK scattering length ||a-0||=13||a1/2-a3/2||=(0.11+0.09-0.04)M-1π (aI for isospin I).
