Runge-Lenz Vector as a 3d Projection of SO(4) Moment Map in Phase Space
Hitoshi Ikemori, Shinsaku Kitakado, Yoshimitsu Matsui +1
We show, using the methods of geometric algebra, that Runge-Lenz vector in the Kepler problem is a 3-dimensional projection of SO(4) moment map that acts on the phase space of 4-di…
Mixing Angle of in Heavy Quark Effective Therory
Yoshimitsu Matsui
The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angle of hadron states in a heavy quark, such as the charm quark (c) and the bottom quark (b). By…
Photonuclear Reactions in Lightning Discovered from Detection of Positrons and Neutrons
Teruaki Enoto, Yuuki Wada, Yoshihiro Furuta +9
Lightning and thundercloud are the most dramatic natural particle accelerators on the Earth. Relativistic electrons accelerated by electric fields therein emit bremsstrahlung gamma…
Non Abelian Vortices as Instantons on Noncommutative Discrete Space
Hitoshi Ikemori, Shinsaku Kitakado, Hideharu Otsu +1
There seems to be close relationship between the moduli space of vortices and the moduli space of instantons, which is not yet clearly understood from a standpoint of the field the…
Business Cycle and Conserved Quantity in Economics
Masa-aki Taniguchi, Masako Bando, Akihiro Nakayama
We propose a dynamical model for business cycle based on an optimal DI model. In the model there exists a conserved quantity, which corresponds to the total energy in a dynamical s…
An Exotic Approach to Hadron Physics
Masako Bando, Yoko Fukase, Jonathan Shock +2
An exotic approach to hadrons is discussed. It is based on the recently developed open-closed string duality explicitly conjectured as the AdS/CFT correspondence. Mesons as well as…
