General Massive Spin-2 on de Sitter Background
Gregory Gabadadze, Alberto Iglesias, Yanwen Shang
We study linearized massive gravity on the de Sitter background. With a small-enough graviton mass this may have had relevance to inflation, or the present-day cosmic acceleration.…
Non Pauli-Fierz Massive Gravitons
Gia Dvali, Oriol Pujolas, Michele Redi
We study general Lorentz invariant theories of massive gravitons. We show that, contrary to the standard lore, there exist consistent theories where the graviton mass term violates…
Gravity Cutoff in Theories with Large Discrete Symmetries
Gia Dvali, Michele Redi, Sergey Sibiryakov +1
We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z_N discrete symmetries. The bound stems from black hole ph…
Pole Mass, Width, and Propagators of Unstable Fermions
Bernd A. Kniehl, Alberto Sirlin
The concepts of pole mass and width are extended to unstable fermions in the general framework of parity-nonconserving gauge theories, such as the Standard Model. In contrast with…
Intrinsic Cutoff and Acausality for Massive Spin 2 Fields Coupled to Electromagnetism
M. Porrati, R. Rahman
We couple a massive spin 2 particle to electromagnetism. By introducing new, redundant degrees of freedom using the Stueckelberg formalism, we extract an intrinsic, model independe…
Electrodynamic Metanuclei
Gregory Gabadadze, Rachel A. Rosen
A relativistic system of electrically charged fermions and oppositely charged massive scalars with no self-interactions, is argued to have a long-lived collective state with a net…
