Observation results by the TAMA300 detector on gravitational wave bursts from stellar-core collapses
Masaki Ando, Koji Arai, Youichi Aso +19
We present data-analysis schemes and results of observations with the TAMA300 gravitational-wave detector, targeting burst signals from stellar-core collapse events. In analyses fo…
Mass and Cross-section Measurements of Chargino at Linear Colliders in Large tan(beta) Case
Yukihiro Kato, Keisuke Fujii, Teruki Kamon +2
The lighter chargino pair production () is one of key processes for determination of supersymmetric parameters at a linear collider. If…
Extended Source Effects in Substructure Lensing
Kaiki Taro Inoue, Masashi Chiba
We investigate the extended source size effects on gravitational lensing in which a lens consists of a smooth potential and small mass clumps (``substructure lensing''). We first c…
Filamentary jets as a cosmic-ray "Zevatron"
Mitsuru Honda, Yasuko S. Honda
Strong, anisotropic turbulence reflecting magnetized filaments is considered, to model the diffusive acceleration of particles by shock waves in active galactic nucleus jets. We ad…
Virtual turning points and bifurcation of Stokes curves for higher order ordinary differential equations
Takashi Aoki, Takahiro Kawai, Shunsuke Sasaki +2
For a higher order linear ordinary differential operator P, its Stokes curve bifurcates in general when it hits another turning point of P. This phenomenon is most neatly understan…
Self-Duality and Phase Structure of the 4D Random-Plaquette Z_2 Gauge Model
Gaku Arakawa, Ikuo Ichinose, Tetsuo Matsui +1
In the present paper, we shall study the 4-dimensional Z_2 lattice gauge model with a random gauge coupling; the random-plaquette gauge model(RPGM). The random gauge coupling at ea…
