Neutrino-electron scattering kernels in isotropic media
Jens Chluba, Bryce Cyr, Michiru Uwabo-Niibo +1
In the early universe, neutrinos undergo many interactions with the particles in the plasma. Key processes are the scattering of neutrinos by free electrons and positrons. In this…
Minimal Majoron Dark Matter from a Discrete Gauge Symmetry
Subaru Fujisawa, Qiuyue Liang, Shigeki Matsumoto +2
We investigate majoron dark matter in a minimal setup, where the Standard Model is extended by three right-handed neutrinos and a complex scalar field. The theory is defined by an…
Pathways and impediments towards a detection of the relic neutrino wind
Andrew J. Long, Michiru Uwabo-Niibo, Masahide Yamaguchi
A direct detection of the cosmic neutrino background (CNB) in laboratories on Earth has been called the ``holy grail'' of experimental neutrino physics, but a still more glorious p…
Multimodal axion emissions from Abelian-Higgs cosmic strings
Naoya Kitajima, Michiru Uwabo-Niibo
We show that axions can be produced from Abelian-Higgs cosmic strings due to the axion-gauge coupling. The strong magnetic field is confined in the string, and the electric field i…
Illuminating the dark universe in the multi-messenger era
Philippe Brax, Anne-Christine Davis, Md Riajul Haque +8
The precision era of multi-messenger astronomy, together with modern astrophysical, cosmological, and gravitational wave observations, increasingly points toward the existence of a…
Effects of New Forces on Scalar Dark Matter Solitons
Alize Sucsuzer, Mark P. Hertzberg, Michiru Uwabo-Niibo
New long range forces acting on ordinary matter are highly constrained. However it is possible such forces act on dark matter, as it is less constrained observationally. In this wo…
