Phenomenological Investigation of Baryon Resonances
The approach to resonance phenomena in nuclear and particle physics is formulated within the R-matrix formalism. The new quantization condition for asymptotic momenta, P, of decay products of a resonance was obtained as well as approximate formula for estimation of partial widths. We concluded that, in order to explain small widths of the so-called narrow dibaryon resonances, one has no need to introduce new hypothesis. The strength of the interaction potential between the decay products at some characteristic distance (about of 0.9 fm) is one of the main components responsible for the width of the resonance.
