Reactor neutrino background in next-generation dark matter detectors

DA Sierra, V De Romeri, CA Ternes - Physical Review D, 2024 - APS
Third-generation dark matter detectors will be fully sensitive to the B 8 solar neutrino flux.
Because of this, the characterization of such a background has been the subject of extensive …

[HTML][HTML] Thermal relic right-handed neutrino dark matter

J Sheng, Y Cheng, TT Yanagida - Physics Letters B, 2024 - Elsevier
It is known that two heavy Majorana right-handed neutrinos are sufficient to generate the
baryon asymmetry in the present universe. Thus, it is interesting to identify the third right …

Prospects for the detection of Dark Matter with Long-lived Mediators in the Sun using the Southern Wide-field Gamma-ray Observatory

M Andrade, J Fagiani, C Siqueira, V de Souza… - arXiv preprint arXiv …, 2024 - arxiv.org
The operation of the next generation of gamma-ray observatories will lead to a great
advance in dark matter searches. In this paper, we use the hidden sectors hypothesis within …

Late-forming black holes and the antiproton, gamma-ray, and anti-helium excesses

M Korwar, S Profumo - arXiv preprint arXiv:2403.18656, 2024 - arxiv.org
Black holes long-lived enough to be the dark matter have temperatures below the MeV.
Since Hawking evaporation is a quasi-thermal process, no GeV emission is predicted to be …

Prediction of the Dark Fermion Mass using Multicritical-Point Principle

Y Matsuoka - arXiv preprint arXiv:2406.07931, 2024 - arxiv.org
This paper proposes a method to determine the effective potential using the multicritical-
point principle (MPP) under the additional scalar field. The MPP is applied to the model in …
