Conformal Killing Tensors, Noether Currents and Higher-Spin Shift Symmetries in (A)dS Space
Kurt Hinterbichler, Samanta Saha, Thomas Yan
For certain mass values, shift symmetries appear among massive higher spin fields propagating on (anti-) de Sitter spacetime. On the one hand, Noether's theorem assigns a set of co…
A Note on the AdS/CFT Equivalence Transformation for Galileons in General Dimensions
Kurt Hinterbichler, Samanta Saha
The AdS/CFT equivalence transformation is a field redefinition that relates the Weyl dilaton and AdS brane realizations of broken conformal symmetry. Acting on theories with second…
Hidden Conformal Symmetry of the Discrete Series Scalars in dS
Kara Farnsworth, Kurt Hinterbichler, Samanta Saha
In dimensional de Sitter space, a scalar field has an infinite tower of special tachyonic mass values at which enhanced shift symmetries appear. After modding out by these shif…
Equivalence of EFTs and Time-Like Extra Dimensions
Kurt Hinterbichler, Samanta Saha
A flat 3-brane probing a five dimensional anti-de Sitter space has the same symmetries and symmetry breaking pattern as one probing a five dimensional de Sitter space with two time…
