NUCLEON-NUCLEON INTERACTION FROM MESON-EXCHANGE AND NUCLEONIC STRUCTURE

We discuss the physics of the Bochum NN potential (Ruhrpot). In contra st to conventional one-boson-exchange, models (OBE) we calculate the p otential within two phases which are (i) meson exchanges at long dista nces and (ii) direct NN interactions, coming from the intrinsic nucleo n structure, at short distances. The interaction vertices are calculat ed in a self-consistent way. The most important resonant two- and thre e-pi correlations are included. As the meson exchange is negligible at high Q2 we have several advantages: (i) reasonable meson scales, (ii) SU(6) limit for vector mesons, (iii) perturbative QCD asymptotic, (iv ) no need for sigma mesons, and (v) very good description of the nucle on-nucleon data.
