Moduli Bounds from Spin-2 Sum Rules
Francesco Bertucci, James Bonifacio, Kurt Hinterbichler
Mirbabayi and Villadoro have provided strong numerical evidence for a universal upper bound on the mass of the lightest scalar field in gravitational Kaluza--Klein (KK) theories. T…
Radial Solutions of Multi-Field de Sitter Galileons
Alice Garoffolo, Mary Gerhardinger, Kurt Hinterbichler +1
We study static, spherically symmetric screening solutions in the -invariant multi-field de Sitter Galileon theory, with matter couplings preserving the internal…
De Sitter Representations
Kurt Hinterbichler
We review the representations of so(1,D), the algebra of isometries of D dimensional de Sitter space. We cover the representations in all D, including mixed symmetry representation…
Manifest Duality Invariance for the Partially Massless Graviton
Kurt Hinterbichler
For a special value of the mass, a massive graviton on de Sitter space acquires an enhanced scalar gauge symmetry, and is called partially massless. The partially massless graviton…
Shift Symmetries in (Anti) de Sitter Space
James Bonifacio, Kurt Hinterbichler, Austin Joyce +1
We construct a class of extended shift symmetries for fields of all integer spins in de Sitter (dS) and anti-de Sitter (AdS) space. These generalize the shift symmetry, galileon sy…
Kaluza-Klein Towers on General Manifolds
Kurt Hinterbichler, Janna Levin, Claire Zukowski
A higher-dimensional universe with compactified extra dimensions admits a four-dimensional description consisting of an infinite Kaluza-Klein tower of fields. We revisit the proble…
