Title: Nonlocal field theory model for nuclear matter

Journal Article · · Physical Review C
; ; ;

Nuclear matter is investigated in the relativistic Hartree approximation to a nonlocal A-E model containing short distance vertex form factors to simulate an underlying QCD substructure. At the Hartree level only the nucleon momentum dependence of the distributed vertex enters and the resulting finite nonlocal field theory model is solved in Euclidean metric with simple Gaussian forms for the so-called sideways form factors. To reproduce saturated nuclear matter the nonlocal model selects form-factor ranges at the nucleon mass scale.
