Reheat Temperature and the Right-handed Neutrino Mass
Takeshi Fukuyama, Tatsuru Kikuchi, Wade Naylor
We discuss the reheating temperature in the instant preheating scenario. In this scenario, at the last stage of inflation, the inflaton field first decays into another scalar field…
Can thick braneworlds be self-consistent?
Masato Minamitsuji, Wade Naylor, Misao Sasaki
We discuss the backreaction of a massless, minimally coupled, quantized scalar field on a thick, two-dimensional de Sitter (dS) brane as an extension of our previous work. We show…
Graviton emission from a higher-dimensional black hole
A. S. Cornell, Wade Naylor, Misao Sasaki
We discuss the graviton absorption probability (greybody factor) and the cross-section of a higher-dimensional Schwarzschild black hole (BH). We are motivated by the suggestion tha…
Constraint on the heavy sterile neutrino mixing angles in the SO(10) model with double see-saw mechanism
Takeshi Fukuyama, Tatsuru Kikuchi, Koichi Matsuda
Constraints on the heavy sterile neutrino mixing angles are studied in the framework of a minimal supersymmetric model with {\it double see-saw mechanism}. A new sin…
Diquark Bose-Einstein condensation
K. Nawa, E. Nakano, H. Yabu
Bose-Einstein condensation (BEC) of composite diquarks in quark matter (the color superconductor phase) is discussed using the quasi-chemical equilibrium theory at a relatively low…
Relativistic Gross-Pitaevskii equation and the cosmological Bose Einstein Condensation
Takeshi Fukuyama, Masahiro Morikawa
We do not know 96% of the total matter in the universe at present. In this paper, a cosmological model is proposed in which Dark Energy (DE) is identified as Bose-Einstein Condensa…
