Abstract:  

The Physics of nuclear matter at high density is a totally uncharted domain. In our past effort, we found that, we combined the topology change which is a robust conclusion in the skyrmion approach to dense nuclear matter and the emergent hidden and local flavor symmetries which are hidden in the matter free space, the nuclear matter properties can be described in a unified effective theory (GnEFT) including, in addition to the Nambu-Goldstone boson pions and the nucleons, the lightest scalar meson and the vector mesons rho and omega. The compact star properties, the mass of the massive neutron star as well as the constraints from the gravitational wave detections can be satisfied. In this talk, I will discuss the main points of the GnEFT and its predictions.
