In all, six parallel sessions were devoted to this topic, ranging in subject matter from the elementary K‐nucleon system to the hypernuclear many‐body problem. The present status of the field was discussed, as were some of the future prospects. There is great promise for learning much new information about the many‐body physics of strong interactions, specifically, nuclear systems in which lambda or sigma hyperon ‘‘impurities’’ have been implanted. However, presently it is clear that if the field is to achieve dramatic new succeses, presently available facilities must be improved significantly.","PeriodicalId":240164,"journal":{"name":"Intersections Between Particles and Nuclear Physics","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121915818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end the E1 sum rules are exhibited for 3 non‐relativistic quarks in a harmonic oscillator model. An excellent fit is obtained to photopion production on free nucleons with an r.m.s. radius 〈r〉≊0.35 F and a constituent quark mass μ=0.37 GeV. Extension of this harmonic oscillator model without additional parameters leads to a Regge trajectory slope of dm2/dJ≊1.1 GeV2, which is just the empirically extracted value. Since γ‐γ scattering has not been observed on nuclear matter in the nucleon E1 region (Eγ=600–800 GeV), some discussion is presented of corresponding M1 measurements in the △ region (Eγ=200–400 MeV).
