Quantum Corrections to Supergravity on AdS2× S2
Abstract
We compute the off-shell spectrum of supergravity on AdS2× S2 by explicit diagonalization of the equations of motion for an effective AdS2 theory where all fields are dualized to scalars and spin-1 2 fermions. Classifying all bulk modes as physical, gauge violating, and pure gauge let us identify boundary modes as physical fields on S2 that are formally pure gauge but with gauge function that is non-normalizable on AdS2. As an application we compute the leading quantum correction to AdS2× S2 as a sum over physical fields including boundary states.
