On the Delta-Nucleon and Rho - Pi Splittings: A QCD-inspired Look in Free Hadrons versus Nuclei

Abstract

Relationships between mass intervals for free hadrons and in nuclei are studied in two theoretical approaches inspired by QCD: naive quark model and skyrmion model, taking one example each from mesons and baryons, that of pi-rho splitting in mesons, and nucleon-Delta splitting in baryons. Possible deconfinement effects in nuclei are examined.
