Finding a system of essential 2-suborbifolds
Yoshihiro Takeuchi, Misako Yokoyama
We make an analogy of Culler-Morgan-Shalen theory. Our main goal is to show that there exists a non-empty system of essential 2-suborbifolds respecting a given splitting of the orb…
The t-singular homology of orbifolds
Yoshihiro Takeuchi, Misako Yokoyama
For an orbifold M we define a homology group, called t-singular homology group t-H_q(M), which depends not only on the topological structure of the underlying space of M, but also…
Direct CP, T and/or CPT violations in the K^0-\bar{K^0} system - Implications of the recent KTeV results on decays -
Y. Takeuchi, S. Y. Tsai
The recent results on the CP violating parameters Re(e'/e) and Δϕ= ϕ_{00}-ϕ_{+-} reported by the KTeV Collaboration are analyzed with a view to constrain CP, T and CPT violations i…
More on Parametrization Relevant to Describe Violation of CP, T and CPT Symmetries in the System
Y. Kouchi, Y. Takeuchi, S. Y. Tsai
To study violation of CP, T and/or CPT symmetries in the systems, one has to parametrize the relevant mixing parameters and decay amplitudes in such a way that each…
Physics Involved in Neutrino Oscillation
Y. Takeuchi, Y. Tazaki, S. Y. Tsai +1
Neutrino oscillation is discussed with emphases placed more on its conceptual aspects. After reviewing the two conventional formulations, referred to here as the same-energy prescr…
