We calculate the energy per particle in infinite neutron matter perturbatively using chiral N3LO two-body potentials plus N2LO three-body forces. The cutoff dependence of the predictions is investigated by employing chiral interactions with different regulators. We find that the inclusion of three-nucleon forces, which are consistent with the applied two-nucleon interaction, leads to a strongly reduced regulator dependence of the results.

    A new open-source calculation engine produces crust-to-core neutron star equations of state and shows that smooth matching choices change predicted radii and masses by several percent.

  2. Core Composition Effects on the QCD Axion Mass Limit from Neutron Star Cooling

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    Varying neutron star core composition with hyperons and Delta resonances mildly affects the QCD axion mass limit from cooling, potentially bringing the DFSZ limit into the IAXO sensitivity window.
