Quantum M 2 → 2 Λ / 3 discontinuity for massive gravity with a Λ term

چکیده
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 massless " limit M 2 → 2Λ/3, as a result of going from five degrees of freedom to four.

Quantum discontinuity for massive spin 3 / 2 with a Λ term
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. Typese...
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 کاملEffective Field Theory for Massive Gravitons and Gravity in Theory Space
We introduce a technique for restoring general coordinate invariance into theories where it is explicitly broken. This is the analog for gravity of the Callan-Coleman-WessZumino formalism for gauge theories. We use this to elucidate the properties of interacting massless and massive gravitons. For a single graviton with a Planck scale MPl and a mass mg, we find that there is a sensible effectiv...
متن کاملA Weak Gravity Conjecture for Scalar Field Theories
Scalars, such as Higgs and inflaton, play significant roles in both particle physics and cosmology. Recently, Vafa et.al. conjectured an upper bound on the strength of gravity relative to gauge forces in quantum gravity [4]. Their conjecture enriches the criteria of consistent effective field theory proposed in [2, 3]. These criteria help to constrain the string landscape [1] in the vast vacua ...
