Gravity in Non-Commutative Geometry
A. H. Chamseddine, G. Felder, J. Fröhlich
We study general relativity in the framework of non-commutative differential geometry. In particular, we introduce a gravity action for a space-time which is the product of a four…
Neutron electric dipole moment due to Higgs exchange in Left-Right symmetric models
D. Chang, Xiao-Gang He, W. -Y. Keung +2
In this paper we study the neutron electric dipole moment (EDM) due to Higgs boson exchange in Left-Right symmetric models. In pseudo-manifest Left-Right symmetric models, the neut…
Grand Unification in Non-Commutative Geometry
A. H. Chamseddine, G. Felder, J. Fröhlich
The formalism of non-commutative geometry of A. Connes is used to construct models in particle physics. The physical space-time is taken to be a product of a continuous four-manifo…
Matter Coupling and Spontaneous Symmetry Breaking in Topological Gravity
T. T. Burwick, A. H. Chamseddine, K. Meissner
Matter is coupled to three-dimensional gravity such that the topological phase is allowed and the (anti-) de Sitter or Poincaré symmetry remains intact. Spontaneous symmetry breaki…
Classical and Quantum Considerations of Two-dimensional Gravity
T. T. Burwick, A. H. Chamseddine
The two-dimensional theory of gravity describing a graviton-dilaton system is considered. The graviton-dilaton coupling can be fixed such that the quantum theory remains free of th…
