Revisiting Cosmological Constraints on Supersymmetric SuperWIMPs
Meera Deshpande, Jan Hamann, Dipan Sengupta +3
SuperWIMPs are extremely weakly interacting massive particles that inherit their relic abundance from late decays of frozen-out parent particles. Within supersymmetric models, grav…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
Light Sterile Neutrinos: A White Paper
K. N. Abazajian, M. A. Acero, S. K. Agarwalla +184
This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.
A Bayesian view of the current status of dark matter direct searches
Chiara Arina, Jan Hamann, Yvonne Y. Y. Wong
Bayesian statistical methods offer a simple and consistent framework for incorporating uncertainties into a multi-parameter inference problem. In this work we apply these methods t…
Cosmology seeking friendship with sterile neutrinos
Jan Hamann, Steen Hannestad, Georg G. Raffelt +2
Precision cosmology and big-bang nucleosynthesis mildly favor extra radiation in the universe beyond photons and ordinary neutrinos, lending support to the existence of low-mass st…
Cosmological axion bounds
Steen Hannestad, Jan Hamann, Alessandro Mirizzi +2
We discuss current cosmological constraints on axions, as well as future sensitivities. Bounds on axion hot dark matter are discussed first, and subsequently we discuss both curren…
