Summary
Possibilities are examined of obtaining information on kaon nuclear coupling constants, without referring to any specific models. The basis for such a type of analyses is the use of analytic properties of the scattering amplitudes. Particularly useful is the forward dispersion relation for the antisymmetric amplitude. The analysis of the K± 12C scattering leads to the conclusion that the corresponding effective coupling constant is significantly larger than the coherent sum of the elementary coupling constants.
Riassunto
Si sono esaminate le possibilità di ottenere informazioni sulle costanti d’accoppiamento kaone-nucleo senza far riferimento a nessun modello specifico. Particolarmente utile è la relazione di dispersione in avanti per l’ampiezza antisimmetrica. L’analisi dello scattering K± 12C porta alla conclusione che la corrispondente costante d’accoppiamento efficace e significativamente più grande della somma coerente di costanti di accoppiamento elementari.

Some of the most recent redeterminations of elementary residues (17) would support even smaller values forγ coh and, thus, larger discrepancy.
This finding coincides with the claim of the authors of ref. (14). However, this coincidence is fortuitous, a result of two cancelling errors in ref. (14): the superfluous factor 2 in the pole term makesγ two times smaller, the unrealistic high-energy model for Imf − makesγ about two times larger.
