Neutron to dark matter decay in neutron stars [PDF]

open access: yesInternational Journal of Modern Physics A, 2018
Recent proposals have suggested that a previously unknown decay mode of the neutron into a dark matter particle could solve the long lasting measurement problem of the neutron decay width. We show that, if the dark particle in neutron decay is the major component of the dark matter in the universe, this proposal is in disagreement with modern ...

Neutron decay, dark matter and neutron stars [PDF]

open access: yesEPJ Web of Conferences, 2019
Following up on a suggestion that decay to a dark matter fermion might explain the 4σ discrepancy in the neutron lifetime, we consider the implications of such a fermion on neutron star structure.

Properties and Dynamics of Neutron Stars and Proto-Neutron Stars [PDF]

open access: yes, 2022
Following new developments in the measurement of gravitational waves from neutron–star mergers and the modification or construction of particle colliders to reach larger densities, we are entering a new era, during which we can begin to understand dense ...

Proton and neutron superfluidity in neutron star matter [PDF]

open access: yesNuclear Physics A, 1992
Abstract The 3 P 2 neutron superfluidity and the 1 S 0 proton superfluidity in neutron star matter are investigated by solving the gap equation exactly for a realistic nucleon-nucleon potential, namely the Argonne v 14 potential. For the 3 P 2 case, our results point to a nearly isotropic pairing function, in close analogy with the rigorous ...

Hybrid halide perovskite neutron detectors

open access: yesScientific Reports, 2021
Interest in fast and easy detection of high-energy radiation (x-, γ-rays and neutrons) is closely related to numerous practical applications ranging from biomedicine and industry to homeland security issues.

Cooling of neutron stars with quark-hadron continuity [PDF]

open access: yesEPJ Web of Conferences, 2022
Neutron stars are high-density objects formed by the gravitational collapse of massive stars, and the whole star can be likened to a giant nucleus. The interior of a neutron star is considered to contain exotic particles and states which do not appear in

FRAGMENTATION OF NEUTRON STAR MATTER [PDF]

open access: yes, 2017
Background: Neutron stars are astronomical systems with nucleons submitted to extreme conditions. Due to the long range coulomb repulsion between protons, the system has structural inhomogeneities. These structural inhomogeneities arise also in expanding systems, where the fragment distribution is highly dependent on the thermodynamic conditions ...

Triplet pairing in neutron matter [PDF]

open access: yesNuclear Physics A, 2001
The separation method developed earlier by us [Nucl. Phys. {\bf A598} 390 (1996)] to calculate and analyze solutions of the BCS gap equation for $^1$S$_0$ pairing is extended and applied to $^3$P$_2$--$^3$F$_2$ pairing in pure neutron matter. The pairing matrix elements are written as a separable part plus a remainder that vanishes when either momentum
