Claims

C1strongest claim

New absolute X-ray yields for several transitions in kaonic copper and, for the first time, in kaonic fluorine are reported; in kaonic fluorine a suppression of the 4→3 transition yield relative to higher-n transitions is observed, providing evidence for the onset of strong-interaction effects already at the n=4 level, from which a conservative lower limit on the corresponding strong-interaction width is derived.

C2weakest assumption

The Geant4 Monte Carlo simulation of the full experimental setup accurately determines the detection efficiencies for the observed X-ray transitions, allowing reliable conversion of measured counts into absolute yields per stopped kaon (abstract, paragraph on data analysis).

C3one line summary

Absolute X-ray yields measured for kaonic copper and fluorine transitions using CZT detectors at DAΦNE, with observed suppression of the 4→3 yield in fluorine yielding a lower limit on strong-interaction width.
