Photoproduction of Nonstrange Baryon Resonances in a Collective U(7) Model

Amiram Leviatan, R. Bijker

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


We present an algebraic description of the geometric structure of baryons in terms of the algebra U (7). We construct a mass operator that preserves the threefold permutational symmetry and discuss a collective model of baryons with the geometry of an oblate symmetric top. This model is applied to the mass spectrum and the photocoupling amplitudes of nonstrange baryon.
