Strong Coupling vs. 4-D Locality in Induced Gravity
We re-examine the problem of strong coupling in a regularized version of DGP (or “brane-induced”) gravity. We find that the regularization of ref. hep-th/0304148 differs from DGP in that it does not exhibit strong coupling or ghosts up to cubic order in the interactions. We suggest that the nonlocal nature of the theory, when written in terms of the 4-D metric, is a plausible reason for this ph...
متن کاملStrong coupling in brane-induced gravity in five dimensions
Brane-induced gravity in five dimensions (Dvali–Gabadadze–Porrati model) exhibits modification of gravity at ultra-large distances, r ≫ rc = M 2 P l/M 3 where M is the five-dimensional gravity scale. This makes the model potentially interesting for explaining the observed acceleration of the Universe. We argue, however, that it has an intrinsic intermediate energy scale (M9/M4 P l) 1/5. At high...
متن کاملTowards a Strong Coupling Liouville Gravity
A possibility of strong coupling quantum Liouville gravity is investigated via infinite dimensional representations of Uqsl(2,C) with q at a root of unity. It is explicitly shown that vertex operator in this model can be written by a tensor product of a vertex operator of the classical Liouville theory and that of weak coupling quantum Liouville theory. Some discussions about the strong couplin...
متن کاملNon-locality and Gravity-induced Cp Violation
We consider a space-time dependent relative phase between the rightand left-handed spinors and show that it results in a violation of locality in the presence of gravity once the demand of parity covariance is dropped. This violation of locality is such that it readily interprets itself as a gravity-induced CP violation, and at the same time confirms an earlier remark by Wigner that a represent...
متن کاملThe Strong-Coupling Expansion in Simplicial Quantum Gravity
ZN4(κ2) ∼ N γ(κ2)−3 4 e μc(κ2)N4 (1 + c1 N4 + ...) (5) when N4 → ∞, where γ determines the critical behavior of the grand-canonical partition function: ZGC ∼ (μc − κ4) 2−γ as κ4 → μc. Simulating this model one observes two phases; a branched polymer phase for κ2 ∼ 1.3, and a crumpled phase for κ2 ∼ 1.3. In the branched polymer phase γ = 12 , whereas in the crumpled phase the sub-leading correct...
