The Devil Went Down to de Sitter: Divergent Effective Field Theory Expansions in Cosmology
Daniele Dorigoni, Laura Engelbrecht, Nadine Nussbaumer +1
Effective field theories (EFTs) in de Sitter space, and in accelerating cosmologies more generally, must capture phenomena absent in flat space, most notably long-range correlation…
Topological modes, non-locality and the double copy
William T. Emond, Laura Engelbrecht, Nathan Moynihan +1
The double copy connects scattering amplitudes and other objects in gauge and gravity theories. Open conceptual issues include whether non-local information in gravity theories can…
Shift Symmetries and AdS/CFT
Erin Blauvelt, Laura Engelbrecht, Kurt Hinterbichler
Massive fields on anti-de Sitter (AdS) space enjoy galileon-like shift symmetries at particular values of their masses. We explore how these shift symmetries are realized through t…
Positivity bounds in vector theories
Claudia de Rham, Laura Engelbrecht, Lavinia Heisenberg +1
Assuming unitarity, locality, causality, and Lorentz invariance of the, otherwise unknown, UV completion, we derive a new set of constraints on the effective field theory coefficie…
Supersymmetric Massive Gravity
Laura Engelbrecht, Callum R. T. Jones, Shruti Paranjape
We initiate a systematic study of the self-interactions of a massive spin-2 "graviton" consistent with up to supersymmetry. Using a recently developed massive on-sh…
