Low-energy Effective Worldsheet theory of a non-Abelian vortex in high-density QCD Revisited: A regular gauge construction
Chandrasekhar Chatterjee, Muneto Nitta
Color symmetry is spontaneously broken in quark matter at high density as a consequence of di-quark condensations with exhibiting color superconductivity. Non-Abelian vortices or c…
Flavor structure, Higgs boson mass and dark matter in supersymmetric model with vector-like generations
Tetsutaro Higaki, Michinobu Nishida, Naoyuki Takeda
We study a supersymmetric model in which the Higgs mass, the muon anomalous magnetic moment and the dark matter are simultaneously explained with extra vector-like generation multi…
Chiral Soliton Lattice and Charged Pion Condensation in Strong Magnetic Fields
Tomas Brauner, Naoki Yamamoto
The Chiral Soliton Lattice (CSL) is a state with a periodic array of topological solitons that spontaneously breaks parity and translational symmetries. Such a state is known to ap…
Cosmological relaxation and high scale inflation
Tetsutaro Higaki, Naoyuki Takeda, Yusuke Yamada
We study whether the relaxion mechanism solves the Higgs hierarchy problem against a high scale inflation or a high reheating temperature. To accomplish the mechanism, we consider…
Topological Defects and nano-Hz Gravitational Waves in Aligned Axion Models
Tetsutaro Higaki, Kwang Sik Jeong, Naoya Kitajima +2
We study the formation and evolution of topological defects in an aligned axion model with multiple Peccei-Quinn scalars, where the QCD axion is realized by a certain combination o…
Modifying the pion mass in the loosely bound Skyrme model
Sven Bjarke Gudnason, Muneto Nitta
We study the loosely bound Skyrme model with the addition of two different pion mass terms; this is the most general potential of polynomial form up to second order in the trace of…
Higgs Boson Mass and Muon g-2 with Strongly Coupled Vector-like Generations
Michinobu Nishida, Koichi Yoshioka
We study the Higgs boson mass and the muon anomalous magnetic moment (the muon ) in a supersymmetric standard model with vector-like generations. The infrared physics of the m…
Coupling between Majorana fermions and Nambu-Goldstone bosons inside a non-Abelian vortex in dense QCD
Chandrasekhar Chatterjee, Mattia Cipriani, Muneto Nitta
Quark matter at high density may exhibit color superconductivity. As magnetic flux tubes in metallic superconductors, color magnetic flux tubes as non-Abelian vortices appear in th…
Quality of the Peccei-Quinn symmetry in the Aligned QCD Axion and Cosmological Implications
Tetsutaro Higaki, Kwang Sik Jeong, Naoya Kitajima +1
We show that the required high quality of the Peccei-Quinn symmetry can be naturally explained in the aligned QCD axion models where the QCD axion arises from multiple axions with…
The QCD Axion from Aligned Axions and Diphoton Excess
Tetsutaro Higaki, Kwang Sik Jeong, Naoya Kitajima +1
We argue that the QCD axion can arise from many aligned axions with decay constants much smaller than the conventional axion window. If the typical decay constant is of {\cal O}{(1…
