Neutrons are forming an external skin in Nuclei and Neutron Stars

This paper provides some pointers that are relevant to a few select topics about neutrons structures, neutron stars, and relationship to QCD, in particular with respect to confinement, and stangelets. Neutron stars observations seem to confirm the apparition of deconfined quark gluon plasma at the core of neutron stars, and the presence of a superconducting layer above, so that the crust and the superconducting/superfluid region can also explain neutron stars glitches.Aspects covered in the paper are related to the multi-fold analysis of QCD and QED, including confinement, asymptotic freedom and the mass gap, for which we provided new intuitive analyses and interpretations. It confirms the ability to deconfine, à la percolation, under high density and pressure, while still hiding colors, and the existence of superconducting phases.A consequence of the short analysis is that we can support a neutron star core that is an hybrid of deconfined quarks and nuclei, plus possibly hyperons, while proposing that strangelets are likely not produced by neutron stars: a good news for the future of normal matter, that otherwise could have been infected by any minuscule strangelets contribution, spelling (locally) the end of matter as we know it, even if it is a slow process.
