INTERPLAY OF COMPETING RESONANCES,
Abstract
When more than two strongly interacting particles are produced in a collision resonances frequently take place between two of these particles: these resonances are observed as bumps in the energy or so-called ''invariants mass'' distributions. How ever, these bumps do not always occur in the phenomena. If a resonance is broad enough, it decays very near its point of production and thus leaves the possiblity open that the other com peting resonance sets in and washes out the observable effects of the first. There is an integral equation which could in a way be inter preted as describing some phenomenon of this kind, but ha ben sold olyin the cae in which the two resonances are kinematically relaed. the general case s stdied using more free parameters, and to investigate to what extent the real behaviour of the system is investigated under variations of these parameters.
