Low-energy pion-nucleus potential in the extended tree-level model for the pion-nucleon interaction

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

Starting from the extended tree-level model for the πN interaction [1] (hereafter ETLM) we demonstrated that the observed local pion-nucleus repulsion arises from the reduction of baryon masses in nucleus due to strong scalar nuclear field [2]. This is rather convincing argument in favour of nuclear relativism because such repulsion has no explanation within the traditional nonrelativistic approach to nucleus.
