Duality and the cosmological constant
A dynamical theory is studied in which a scalar field φ in Einstein-Minkowski space is coupled to the four-velocity Nμ of a preferred inertial observer in that space. As a consistent requirement on this coupling we study a principle of duality invariance of the dynamical mass-term of φ at some universal length in the smalldistance regime. In the large-distance regime duality breaking can be int...
متن کاملVanishing Cosmological Constant via Gravitational S-Duality
We study S-duality transformations that mix the graviton with various forms of matter. In the case of matter in the form of a 3-form field, the dual of an (A)dS space time – with arbitrary curvature – is seen to be flat Minkowski space time, if the 3-form field has vanishing field strength before the duality transformation. Then we show that the Schwarzschild metric can be obtained as a suitabl...
متن کاملGeneralized Gravitational S-Duality and the Cosmological Constant Problem
We study S-duality transformations that mix the Riemann tensor with the field strength of a 3-form field. The dual of an (A)dS space time – with arbitrary curvature – is seen to be flat Minkowski space time, if the 3-form field has vanishing field strength before the duality transformation. It is discussed whether matter could couple to the dual metric, related to the Riemann tensor after a dua...
متن کاملCosmological Constant as an S-duality Goldstone Mode
For vacua in type IIB string moduli space parameterized by the coupling constant, we propose a scheme for interpretation of the cosmological term in type IIB superstrings as a Goldstone mode from the spontaneous symmetry breaking of SL(2, Z) to a Fuchsian subgroup of degree one, Γh. The moduli space Σh = Γh\H has a radial direction with a massive Goldstone mode, and the contribution to the posi...
متن کاملSelf duality of the gauge field equations and the cosmological constant
This paper considers the Einstein equations coupled with the nonabelian gauge and Higgs fields. It is shown that, when cosmic string solutions are sought in the Einstein-Georgi-Glashow system and the Einstein-Weinberg-Salam system governing the gravitational-electromagnetic-weak interaction forces, the self duality conditions lead to positive values of the cosmological constant which can be exp...
