Quantum discontinuity between zero and infinitesimal graviton mass with a Λ term

چکیده
We show that the recently demonstrated absence of the usual discontinuity for massive spin 2 with a Λ term is an artifact of the tree approximation, and that the discontinuity reappears at one loop.

Effective Lagrangian from Higher Curvature Terms: Absence of vDVZ Discontinuity in AdS Space
We demonstrate that the van Dam-Veltman-Zakharov discontinuity arising in the M2 → 0 limit of the massive graviton through an explicit Pauli-Fierz mass term is absent in anti de Sitter space, in particular, when graviton acquires mass spontaneously from the higher curvature terms. More generally, the massless limit M2 → 0 is attained faster than the cosmological constant Λ → 0, and the absence ...
متن کاملNonperturbative Continuity in Graviton Mass versus Perturbative Discontinuity
We address the question whether a graviton could have a small nonzero mass. The issue is subtle for two reasons: there is a discontinuity in the mass in the lowest tree-level approximation, and, moreover, the nonlinear four-dimensional theory of a massive graviton is not defined unambiguously. First, we reiterate the old argument that for the vanishing graviton mass the lowest tree-level approx...
متن کاملO ct 2 00 6 The nature of Λ and the mass of the graviton : A critical view
The existence of a non-zero cosmological constant Λ gives rise to controversial interpretations. Is Λ a universal constant fixing the geometry of an empty universe, as fundamental as the Planck constant or the speed of light in the vacuum? Its natural place is then on the left-hand side of the Einstein equation. Is it instead something emerging from a perturbative calculus performed on the metr...

متن کاملCosmic Strings in a Braneworld Theory with Metastable Gravitons
If the graviton possesses an arbitrarily small (but nonvanishing) mass, perturbation theory implies that cosmic strings have a nonzero Newtonian potential. Nevertheless in Einstein gravity, where the graviton is strictly massless, the Newtonian potential of a cosmic string vanishes. This discrepancy is an example of the van Dam–Veltman–Zakharov (VDVZ) discontinuity. We present a solution for th...
