Description

The KKLT scenario in a warped throat, if consistent, provides a concrete counterexample to both the AdS scale separation and the dS swampland conjectures. In this talk I will analyze the relevant effective field theory for the conifold modulus and the overall Kahler modulus that both have exponentially small masses. In particular, I will focus on KK modes that have masses below the mass scale set by the conifold modulus. We find that integrating out the KK modes leads to one-loop corrections to the moduli kinetic terms which are of the same functional form as their tree level values. Implications for the consistency of the KKLT scenario are discussed. Finally I will comment on the role of KK modes for the emergence of kinetic terms in quantum gravity.
