Some results on strongly operator convex functions and operator monotone functions
Lawrence G. Brown, Mitsuru Uchiyama
This paper concerns three classes of real-valued functions on intervals, operator monotone functions, operator convex functions, and strongly operator convex functions. Strongly op…
Semi-aligned two Higgs doublet model
Naoyuki Haba, Hiroyuki Umeeda, Toshifumi Yamada
In the left-right symmetric model based on gauge symmetry, there appear heavy neutral scalar particles mediating quark flavor changing neut…
Sneutrinos as Mixed Inflaton and Curvaton
Naoyuki Haba, Tomo Takahashi, Toshifumi Yamada
We investigate a scenario where the supersymmetric partners of two right-handed neutrinos (sneutrinos) work as mixed inflaton and curvaton, motivated by the fact that the curvaton…
Classification of almost Yamabe solitons in Euclidean spaces
Tatsuya Seko, Shun Maeta
In this paper, we completely classify almost Yamabe solitons on hypersurfaces in Euclidean spaces arisen from the position vector field. Some results of almost Yamabe solitons with…
Complete Yamabe solitons with finite total scalar curvature
Shun Maeta
In this paper, we show that steady or shrinking complete gradient Yamabe solitons with finite total scalar curvature and non-positive Ricci curvature are Ricci flat. Moreover, unde…
Individual eigenvalue distributions of crossover chiral random matrices and low-energy constants of SU(2)U(1) lattice gauge theory
Takuya Yamamoto, Shinsuke M. Nishigaki
We compute individual distributions of low-lying eigenvalues of a chiral random matrix ensemble interpolating symplectic and unitary symmetry classes by the Nyström-type method of…
Relaxation Dynamics of a Granular Pile on a Vertically-Vibrating Plate
Daisuke Tsuji, Michio Otsuki, Hiroaki Katsuragi
Nonlinear relaxation dynamics of a vertically-vibrated granular pile is experimentally studied. In the experiment, the flux and slope on the relaxing pile are measured by using a h…
Phenomenological Aspects of Possible Vacua of a Neutrino Flavor Model
Takuya Morozumi, Hideaki Okane, Hiroki Sakamoto +3
We discuss a supersymmetric model with discrete flavor symmetry . The additional scalar fields which contribute masses of leptons in the Yukawa terms are introduced…
Heavy neutrino mixing in the T2HK, the T2HKK and an extension of the T2HK with a detector at Oki Islands
Yugo Abe, Yusuke Asano, Naoyuki Haba +1
We study the discovery potential for the mixing of heavy isospin-singlet neutrinos in extensions of the Tokai-to-Kamioka (T2K) experiment: The Tokai-to-Hyper-Kamiokande (T2HK), the…
Multiple-point principle realized with strong dynamics
Naoyuki Haba, Toshifumi Yamada
We present a novel extension of the Standard Model which fulfills the multiple-point principle without contradicting the Higgs particle mass measurement. In the model, the scalar p…
Strong dynamics in a classically scale invariant extension of the Standard Model with flatland
Naoyuki Haba, Toshifumi Yamada
We investigate the scenario where the Standard Model is extended with classical scale invariance, which is broken by chiral symmetry breaking and confinement in a new strongly-coup…
