Parity violation, the neutron radius of lead, and neutron stars

Jorge Piekarewicz

- 17 Jul 2007 -

European Physical Journal A

TL;DR: The parity radius experiment at the Jefferson Laboratory offers an attractive electro-weak alternative to the hadronic program and promises to measure the neutron radius of 208Pb accurately and model independently via parity-violating electron scattering.

Physical Review C

TL;DR: In this paper , the properties of two different matter compositions: nucleonic matter with delta baryons and nucleonic material with hyperons and delta baries are analyzed. And the authors show that with a convenient choice of parameters, the existence of deltic stars with 80% of delta Baryons at the center of the star is possible, however, the presence of hyperons lowers the deltaBaryon fraction to values below 20% at the centre and below 30% at 2-3 saturation densities.

Neutron star properties with careful parametrization in the vector and axial-vector meson extended linear sigma model

TL;DR: In this article , a vector and axial-vector meson extended quark-meson model was used to describe quark matter in the core of heavy neutron stars, and it was shown that an additional parameter constraint is necessary in the quark model to ensure chiral restoration at high densities.

Systematic errors due to quasiuniversal relations in binary neutron stars and their correction for unbiased model selection

Rahul Kashyap, +2 more

TL;DR: In this paper , the authors quantify the systematic errors arising from the application of EoS-independent quasi-universal relations in the estimation of neutron star tidal deformabilities and radii from gravitational-wave measurements and introduce a strategy to correct for the systematic biases in the inferred radii.
