Broken Democracy with Intermediate Residual Symmetry and Random Perturbations
Neil D. Barrie, Shao-Feng Ge, Tsutomu T. Yanagida
The democratic mass matrix is an intriguing possibility for explaining the observed fermion mixings due to its inherent hierarchical mass eigenvalues and large mixing angles. Never…
Implications for Dark Matter Direct Detection in the Presence of LIGO-Motivated Primordial Black Holes
Mark P. Hertzberg, Enrico D. Schiappacasse, Tsutomu T. Yanagida
We discuss formation of dark matter (DM) mini-halos around primordial black holes (PBHs) and its implication on DM direct detection experiments, including axion searches. Motivated…
Quintessence Axion Dark Energy and a Solution to the Hubble Tension
Gongjun Choi, Motoo Suzuki, Tsutomu T. Yanagida
We present a model in which the question about a nature of the dark energy and the recently raised Hubble tension can be addressed at once. We consider the electroweak axion in the…
Solving the strong CP problem with horizontal gauge symmetry
Gongjun Choi, Tsutomu T. Yanagida
We present a solution to the strong CP problem, which relies on the horizontal gauge symmetry and CP invariance in a full theory. Similar to other Nelson-Barr type solutions, CP vi…
A Dynamical Solution to the Axion Domain Wall Problem
Masahiro Ibe, Shin Kobayashi, Motoo Suzuki +1
The domain wall problem and the isocurvature problem restrict possible combinations of axion models and inflation models. In this paper, we considered a new mechanism which solves…
Unification for the Darkly Charged Dark Matter
Ayuki Kamada, Masaki Yamada, Tsutomu T. Yanagida
We provide a simple UV theory for a Dirac dark matter with a massless Abelian gauge boson. We introduce a single fermion transforming as the representation in the SO(10)$…
