Do Delta Baryons Play a Role in Neutron Stars?

Abstract

The presence of exotic hadrons, such as hyperons and Δ\Delta isobars, in the dense nuclear matter in their cores has been shown to produce important changes in the properties of neutron stars. Within the quark-meson coupling model, we show that the many-body forces generated by the change in the internal quark structure of the baryons in the strong scalar mean fields generated in dense nuclear matter prohibit the appearance of Δ\Delta isobars.
