The neutrino masses and the change of allowed parameter region in universal extra dimension models
Shigeki Matsumoto, Joe Sato, Masato Senami +1
Relic abundance of dark matter is investigated in the framework of universal extra dimension models with right-handed neutrinos. These models are free from the serious Kaluza-Klein…
Impact of non-standard neutrino interactions on future oscillation experiments
Joachim Kopp, Manfred Lindner, Toshihiko Ota +1
We study the performance of reactor and superbeam neutrino experiments in the presence of non-standard interactions (NSI). We find that for some non-standard terms, reactor and sup…
Chiral Symmetry Breaking in Brane Models
Norio Horigome, Madoka Nishimura, Yoshiaki Tanii
We discuss the chiral symmetry breaking in general intersecting Dq/Dp brane models consisting of N_c Dq-branes and a single Dp-brane with an s-dimensional intersection. There exist…
Disordered ground states in a quantum frustrated spin chain with side chains
Ken'ichi Takano, Kazuo Hida
We study a frustrated mixed spin chain with side chains, where the spin species and the exchange interactions are spatially varied. A nonlinear sigma model method is formulated for…
Examining exotic structure of proton-rich nucleus Al
D. Q. Fang, W. Guo, C. W. Ma +24
The longitudinal momentum distribution (P_{//}) of fragments after one-proton removal from ^{23} Al and reaction cross sections (σ_R) for ^{23,24} Al on carbon target at 74A MeV ha…
Non-standard neutrino interactions in reactor and superbeam experiments
Joachim Kopp, Manfred Lindner, Toshihiko Ota +1
The formalism of non-standard four-fermion interactions provides a convenient, model-independent way of parameterizing a wide class of ``new physics'' scenarios. In this article, w…
