Description
In this talk I will discuss some recent advances in an effective theory of QCD at low energies, where nuclei and baryons are described by topological soliton solutions known as Skyrmions.
Following the great success of coupling the rho mesons to the Skyrme field (which provided more realistic nuclear binding energies for the model and the triggering of nuclear clustering), we have recently shown the role that the leading $\rho \pi$ interaction term can play in the study of dense nuclear matter. This contribution, motivated by a theoretical construction from a Yang-Mills theory in one higher dimension, astonishingly reduces the compression modulus that the Skyrme model provides from the very large value of $K_0 ≃1080$ MeV to a more physical $K_0 ≃351$ MeV.
