effects on angles determination at a factory
T. Kurimoto, A. Tomita, S. Wakaizumi
The right-handed charged current gauge boson can affect significantly on the determination of the violation angles to be measured at factories if the right-handed cu…
GKZ-Generalized Hypergeometric Systems in Mirror Symmetry of Calabi-Yau Hypersurfaces
S. Hosono, B. H. Lian, S. -T. Yau
We present a detailed study of the generalized hypergeometric system introduced by Gel'fand, Kapranov and Zelevinski (GKZ-hypergeometric system) in the context of toric geometry. G…
Gauge Theory of Massive Tensor Field
Shinji Hamamoto
In order to construct a massive tensor theory with a smooth massless limit, we apply the Batalin-Fradkin algorithm to the ordinary massive tensor theory. By introducing an auxiliar…
Perturbative QCD estimation of the branching ratio
Marina-Aura Dariescu, C. Dariescu
Working in a perturbative QCD model approach, we obtain the essential form factor of the radiative transition and estimate the branching ratio $BR(B \righta…
A Toy Model Approach to the Canonical Non-perturbative Quantization of the Spatially Flat Robertson-Walker Spacetimes with Cosmological Constant
C. Dariescu, S. Hamamoto, Marina-Aura Dariescu
We present a toy model approach to the canonical non-perturbative quantization of the spatially-flat Robertson-Walker Universes with cosmological constant, based on the fact that s…
Higher Derivatives and Canonical Formalism
Shinji HAMAMOTO
A canonical formalism for higher-derivative theories is presented on the basis of Dirac's method for constrained systems. It is shown that this formalism shares a path integral exp…
