Dynamical Stability of Six-dimensional Warped Flux Compactification
Hiroyuki Yoshiguchi, Shinji Mukohyama, Yuuiti Sendouda +1
We show the dynamical stability of a six-dimensional braneworld solution with warped flux compactification recently found by the authors. We consider linear perturbations around th…
Warped Flux Compactification and Brane Gravity
Shinji Mukohyama, Yuuiti Sendouda, Hiroyuki Yoshiguchi +1
We find a simple exact solution of 6-dimensional braneworld which captures some essential features of warped flux compactification, including a warped geometry, compactification, a…
Propagation of Ultra-High Energy Cosmic Rays above eV in a Structured Extragalactic Magnetic Field and Galactic Magnetic Field
Hajime Takami, Hiroyuki Yoshiguchi, Katsuhiko Sato
We present numerical simulations on propagation of Ultra-High Energy Cosmic Rays (UHECRs) above eV in a structured extragalactic magnetic field (EGMF) and simulate their…
Quantization of scalar perturbations in brane-world inflation
Hiroyuki Yoshiguchi, Kazuya Koyama
We consider a quantization of scalar perturbations about a de Sitter brane in a 5-dimensional anti-de Sitter (AdS) bulk spacetime. We first derive the second order action for a mas…
Statistical Significance of Small Scale Anisotropy in Arrival Directions of Ultra-High Energy Cosmic Rays
Hiroyuki Yoshiguchi, Shigehiro Nagataki, Katsuhiko Sato
Recently, the High Resolution Fly's Eye (HiRes) experiment claims that there is no small scale anisotropy in the arrival distribution of ultra-high energy cosmic rays (UHECRs) abov…
Bulk gravitational field and dark radiation on the brane in dilatonic brane world
Hiroyuki Yoshiguchi, Kazuya Koyama
We discuss the connection between the dark radiation on the brane and the bulk gravitational field in a dilatonic brane world model proposed by Koyama and Takahashi where the exact…
