No Van Dam - Veltman - Zakharov Discontinuity for Supergravity in Ads Space

چکیده
Adding explicit mass terms for the spin 2 and spin 3/2 field of N = 1 anti-de Sitter supergravity, the limit M → 0 for these mass terms is smooth: there is no van DamVeltman-Zakharov mass discontinuity in the propagators when the cosmological constant is non-vanishing.

No Van Dam - Veltman - Zakharov Discontinuity in Ads Space
We prove that the van Dam-Veltman-Zakharov discontinuity arising in the massless limit of massive gravity theories is peculiar to Minkowski space and it is not present in Anti De Sitter space, where the massless limit is smooth. More generally, the massless limit is smooth whenever the square of the graviton mass vanishes faster than the cosmological constant.
متن کاملFully Covariant Van Dam - Veltman - Zakharov Discontinuity , and Absence Thereof
In both old and recent literature, it has been argued that the celebrated van Dam-Veltman-Zakharov (vDVZ) discontinuity of massive gravity is an artifact due to linearization of the true equations of motion. In this letter, we investigate that claim. First, we exhibit an explicit –albeit somewhat arbitrary– fully covariant set of equations of motion that, upon linearization, reduce to the stand...
متن کاملEffective 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 کاملQuantum M 2 → 2 Λ / 3 discontinuity for massive gravity with a Λ term
In a previous paper we showed that the absence of the van Dam-Veltman-Zakharov discontinuity as M 2 → 0 for massive spin-2 with a Λ term is an artifact of the tree approximation, and that the discontinuity reappears at one loop, as a result of going from five degrees of freedom to two. In this paper we show that a similar classical continuity but quantum discontinuity arises in the " partially ...

Cosmologically motivated theories that explain small acceleration rate of the Universe via modification of gravity at very large, horizon or super-horizon distances, can be tested by precision gravitational measurements at much shorter scales, such as the Earth-Moon distance. Contrary to the naive expectation the predicted corrections to the Einsteinian metric near gravitating sources are so si...
