How can CP violation in the neutrino sector be large in a symmetric model?
Yoshio Koide, Hiroyuki Nishiura
Based on a neutrino mass matrix model in which a 2-3 symmetry is only broken by a phase parameter, it is investigated how the lepton mixing matrix can deviate from the so-called tr…
Black Holes in the Dilatonic Einstein-Gauss-Bonnet Theory in Various Dimensions IV - Topological Black Holes with and without Cosmological Term
Nobuyoshi Ohta, Takashi Torii
We study black hole solutions in the Einstein gravity with Gauss-Bonnet term, the dilaton and a positive "cosmological constant" in various dimensions. Physically meaningful black…
One-neutron removal strength of 7He into 6He using the complex scaling method
Takayuki Myo, Ryosuke Ando, Kiyoshi Kato
We study the one-neutron removal strength of the 7He ground state, which provides us with the 6He-n component in 7He. The He isotopes are described on the basis of the 4He+Xn clust…
Black Objects and Hoop Conjecture in Five-dimensional Space-time
Yuta Yamada, Hisa-aki Shinkai
We numerically investigated the sequences of initial data of thin spindle and thin ring in five-dimensional space-time in the context of the cosmic censorship conjecture. We modele…
Coulomb Breakup Reactions in Complex-Scaled Solutions of the Lippmann-Schwinger Equation
Yuma Kikuchi, Takayuki Myo, Masaaki Takashina +2
We propose a new method to describe three-body breakups of nuclei, in which the Lippmann-Schwinger equation is solved combining with the complex scaling method. The complex-scaled…
Measuring the lower bound of the neutrino mass at the LHC in Higgs triplet model
Hiroyuki Nishiura, Takeshi Fukuyama
We show in the framework of Higgs triplet model that the lower bound of the neutrino mass is obtained if we can measure at the LHC.
