Approximate Flavor Symmetry in Supersymmetric Model
Zhijian Tao
We investigate the maximal approximate flavor symmetry in the framework of generic minimal supersymmetric standard model. We consider the low energy effective theory of the flavor…
New Types of Accessible Environmental Influence on Neutrino Oscillation
Chao-Hsi Chang, Hui-Shi Dong, Xi-Chen Feng +3
To describe possible effects of medium, besides the hamiltonian introduced by Mikheev, Smirnov and Wolfenstein (MSW), in principle, there may exist new terms in the evolution equat…
Cosmological Relics of the High Energy Cold Dark Matter Particle in the Universe
Xue-Qian Li, Zhijian Tao
We demonstrate that if the universe is dominated by the massive cold dark matter, then besides the generally believed thermal distribution of the dark matter relics, there may exis…
Long Distance Contributions to B-Decays into Higher K-Resonances
Mohammad R. Ahmady, Dongsheng Liu, Zhijian Tao
We use the new symmetries in the heavy quark limit to calculate the exclusive B-decays where are higher resonances of K-meson. We then estimate the long…
