Goldstone Boson Emission From Nucleon Cooper Pairing in Neutron Stars and Constraints on the Higgs Portal Models
When a neutron star cools to below the critical temperature for the onset of superfluidity, nucleon pair breaking and formation (PBF) processes become the dominant mechanism for neutrino emission, while the modified URCA and the nuclear bremsstrahlung processes are suppressed.

| description | When a neutron star cools to below the critical temperature for the onset of
superfluidity, nucleon pair breaking and formation (PBF) processes become the
dominant mechanism for neutrino emission, while the modified URCA and the
nuclear bremsstrahlung processes are suppressed. The PBF processes in neutron
stars have also been used to set upper limits on the properties of axions,
which are comparable to those set by supernova SN 1987A. We apply this
constraint on Weinberg's Higgs portal model, in which the dark radiation
particles (the Goldstone bosons) and the dark matter candidate (a Majorana
fermion) interact with the Standard Model (SM) fields solely through the mixing
of the SM Higgs boson and a light Higgs boson. We compare the Goldstone boson
emissivity with that of the neutrinos by considering several superfluid gap
models for the neutron singlet-state pairing in the neutron star inner crust,
as well as in the core region. We find that the PBF processes in the superfluid
neutron star interior can indeed probe Weinberg's Higgs portal model in a new
parameter space region. Together with our previous works on the constraints
from supernovae and gamma-ray bursts, this study demonstrates further the
competitiveness and complementarity of astrophysics to laboratory particle
physics experiments. |
