Abstract

Nuclear matter calculations in a chiral hadronic model have beenperformed. It has been found that the scalar and the vector potentialsand binding energies per nucleon in the chiral hadronic model are veryclose to those of the microscopic relativistic Brueckner–Hartree–Fockcalculations. The good results for finite nuclei can be obtained in themean field approximation only if scalar mass ms and coupling constantgs have been improved with the fixed values of cs2≡gs2(M/ms)2 as those given by the original parameter sets of the chiralhadronic model. Then the chiral hadronic model is extended to lambdahypernuclei. Our results predicted by the chiral hadronic model arecompared with those by the nonlinear Walecka model. It has been shownthat the hadronic model can also be used to describe lambda hypernucleisuccessfully.
