Moduli Dynamics in Effective Nested Warped Geometry in Four Dimensions and Some Cosmological Implications

We analyze the effective four-dimensional dynamics of the extra-dimensional moduli fields in curved braneworlds having nested warping, with particular emphasis on the doubly warped model which is interesting in the light of current collider constraints on the mass of the Kaluza-Klein graviton. The p...

Description
Summary:We analyze the effective four-dimensional dynamics of the extra-dimensional moduli fields in curved braneworlds having nested warping, with particular emphasis on the doubly warped model which is interesting in the light of current collider constraints on the mass of the Kaluza-Klein graviton. The presence of a non-zero brane cosmological constant (\(\Omega\)) naturally induces an effective moduli potential in the four-dimensional action, which shows distinct features in dS (\(\Omega>0\)) and AdS (\(\Omega
