Probing Majoron Dark Matter with Gravitational Wave Detectors
Ippei Obata, Tsutomu T. Yanagida
The Majoron is a hypothetical (pseudo) Nambu-Goldstone boson arising from the spontaneous breaking of a global lepton number symmetry, and is known as a candidate for dark matter i…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Searches for ultralight vector and axion dark matter with KAGRA
Yuta Michimura, Takumi Fujimori, Hiroki Fujimoto +10
We have proposed using laser interferometric gravitational wave detectors to search for ultralight vector and axion dark matter. Vector dark matter can be probed through oscillatin…
Axionic defects in the CMB: birefringence and gravitational waves
Ricardo Z. Ferreira, Silvia Gasparotto, Takashi Hiramatsu +2
The evidence for a non-vanishing isotropic cosmic birefringence in recent analyses of the CMB data provides a tantalizing hint for new physics. Domain wall (DW) networks have recen…
Peaky Production of Light Dark Photon Dark Matter
Yuichiro Nakai, Ryo Namba, Ippei Obata
We explore a mechanism to produce a light dark photon dark matter through a coupling between the dark photon field and a spectator scalar field which plays no role in the inflation…
Axion dark matter search using arm cavity transmitted beams of gravitational wave detectors
Koji Nagano, Hiromasa Nakatsuka, Soichiro Morisaki +3
Axion is a promising candidate for ultralight dark matter which may cause a polarization rotation of laser light. Recently, a new idea of probing the axion dark matter by optical l…
