Revisiting the Number-Theory Dark Matter Scenario and the Weak Gravity Conjecture
Kazunori Nakayama, Fuminobu Takahashi, Tsutomu T. Yanagida
We revisit the number-theory dark matter scenario where one of the light chiral fermions required by the anomaly cancellation conditions of U(1)_{B-L} explains dark matter. Focusin…
Gaugino Mediation Scenarios for Muon and Dark Matter
Peter Cox, Chengcheng Han, Tsutomu T. Yanagida +1
We explore the possibility that the muon anomaly and the nature of dark matter can be simultaneously explained within the framework of gaugino mediation, focusing on bino-lik…
Quintessence Axion Revisited in Light of Swampland Conjectures
Masahiro Ibe, Masahito Yamazaki, Tsutomu T. Yanagida
We point out that the swampland conjectures, forbidding the presence of global symmetries and (meta-)stable de Sitter vacua within quantum gravity, pick up a dynamical axion for th…
Self-interacting dark matter with a vector mediator: kinetic mixing with U(1) gauge boson
Ayuki Kamada, Masaki Yamada, Tsutomu T. Yanagida
A spontaneously broken hidden U(1) gauge symmetry can explain both the dark matter stability and the observed relic abundance. In this framework, the light gauge boson can medi…
Do We Live in the Swampland?
Hitoshi Murayama, Masahito Yamazaki, Tsutomu T. Yanagida
A low-energy effective theory is said to be in the swampland if it does not have any consistent UV completion inside a theory of quantum gravity. The natural question is if the sta…
Focus Point Gauge Mediation without a Severe Fine-tuning
Tsutomu T. Yanagida, Norimi Yokozaki
We consider focus point gauge mediation within the framework of the next-to-minimal supersymmetric standard model, which substantially reduces the degree of fine-tuning for the ele…
