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 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 for Massive Gravity with a Cosmological Term
We report on the recent work on the van Dam-Veltman-Zakharov discontinuity for massive and partially massless gravitons in A(dS) space at one-loop. The question of whether the graviton has a small non-zero mass or exactly zero mass has been addressed by van Dam and Veltman, and Zakharov[l]. The difference is physically detectible, e.g. by effect on bending of light by the sun. The case for non-...
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 کاملBlack Holes with Quantum Massive Spin-2 Hair
We show that black holes can posses a long range quantum mechanical hair associated with a massive spin-2 field, which can be detected by a stringy generalization of the Aharovon-Bohm effect, in which a string loop lassoes the black hole. The long distance effect persist for arbitrarily high mass of the spin-2 field. An analogous effect is exhibited by a massive antisymmetric two-form field. We...
