On Fermionic T-duality of Sigma modes on AdS backgrounds
Chen-guang Hao, Bin Chen, Xing-chang Song
We study the fermionic T-duality symmetry of integrable Green-Schwarz sigma models on AdS backgrounds. We show that the sigma model on background is self-dual und…
Flat Currents of the Green-Schwarz Superstrings in AdS_5 x S^1 and AdS_3 x S^3 backgrounds
Bin Chen, Ya-Li He, Peng Zhang +1
We construct a one-parameter family of flat currents in AdS_5 x S^1 and AdS_3 x S^3 Green-Schwarz superstrings, which would naturally lead to a hierarchy of classical conserved non…
The GEMS Approach to Stationary Motions in the Spherically Symmetric Spacetimes
Hong-Zhi Chen, Yu Tian, Yi-Hong Gao +1
We generalize the work of Deser and Levin on the unified description of Hawking radiation and Unruh effect to general stationary motions in spherically symmetric black holes. We ha…
The Narrow Pentaquark As The First Non-planar Hadron With the Diamond Structure And Negative Parity
Xing-Chang Song, Shi-Lin Zhu
Using the picture of the flux tube model, we propose that the pentaquark as the first candidate of the three-dimensional non-planar hadron with the extremely stable diamond s…
Topological Charge of Noncommutative ADHM Instanton
Yu Tian, Chuan-Jie Zhu, Xing-Chang Song
We analytically calculate the topological charge of the noncommutative ADHM U(N) k-instanton using the Corrigan's identity and find that the result is exactly the instanton number…
Dirac Neutrino Masses in NCG
Changhui Li, Haogang Ding, Jian Dai +1
Several models in NCG with mild changes to the standard model(SM)are introduced to discuss the neutrino mass problem. We use two constraints, Poincar duality and gauge a…
