Quantum discontinuity for massive spin 3 / 2 with a Λ term
نویسنده
چکیده
We show that the recently demonstrated absence of the van Dam-VeltmanZakharov discontinuity for massive spin 3/2 with a Λ term is an artifact of the tree approximation, and that the discontinuity reappears at one loop. As a numerical check on the calculation, we rederive the vanishing of the oneloop beta function for D = 11 supergravity on AdS4×S level-by-level in the Kaluza-Klein tower.

Quantum 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 ...
متن کاملQuantum discontinuity between zero and infinitesimal graviton mass with a Λ term
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.
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 کاملThe massive Elko spinor field in the de Sitter braneworld model
The Elko spinor field is a spin 1/2 fermionic quantum field with a mass dimension introduced as a candidate of dark matter. In this work, we study the localization of Elko fields on a de Sitter thick brane constructed by a canonical or phantom scalar field. By presenting the mass-independent potentials of Kaluza-Klein (KK) modes in the corresponding Schrödinger equations, it is shown that the E...
متن کاملNewtonian Counterparts of Spin 2 Massless Discontinuities S . Deser and Bayram Tekin
Massive spin 2 theories in flat or cosmological ( Λ 6= 0) backgrounds are subject to discontinuities as the masses tend to zero. We show and explain why their Newtonian limits do not inherit this behaviour. On the other hand, conventional “Newtonian cosmology” ( where Λ is a constant source of the potential ) displays quite different discontinuities; in particular Λ is totally removable for any...
