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…

Scale and Conformal Invariance on (A)dS
Kara Farnsworth, Kurt Hinterbichler, Ondrej Hulik
We examine the question of scale versus conformal invariance on maximally symmetric curved backgrounds and study general 2-derivative conformally invariant free theories of vectors…
