## Is a Non Zero “LOWER” Order Graviton Mass Derivable in Brane Theory Settings and Kaluza Klein Graviton Models?

**Authors:** A.W. Beckwith

The lowest order mass for a KK graviton, as a non zero product of two branes interacting via a situation similar to Steinhardt’s ekpyrotic universe is obtained, as to an alternative to the present dogma specifying that gravitons must be massless. The relative positions as to the branes gives a dynamical picture as to how lowest order KK gravitons could be affected by contraction and then subsequent expansion. And the solution picked is for with a non zero lowest order mass for a KK graviton permits modeling of gravitons via a dynamical Casmir effect which we generalize using Durrer’s 2007 work. Anti-de-Sitter braneworld.construction is what is used to model the Casmir effect. This analysis is taken in AdS5 geometry while assuming that blue spectrum treatment of gravitons no longer holds.
