Summary: | <p align="justify">The first idea about using extra dimension was proposed by Kaluza-Klein. Brane theory was one of theory talk about extra dimensions. It said that our universe is like a membrane n dimensions covered by (n+1) bulk. In 1999, Lisa Randall and Raman Sundrum proposed a model talk about it to answered one of Higgs Hierarchy Problem in particle physics; an explanation about the weakness of the gravitational interactions compared to others fundamental interactions. Someday, this model well-known as Randall-Sundrum model. In RS model said that all particles was trapped in brane, except graviton. RS model was identified by the RS metric that described interval between 2 points in spacetime. There is a problem in RS model, specifically in localization. Because of that there are some changes in RS metric called, RS metric modified. There are some differencies between RS metric original and RS metric modified which the Ricci scalar also will be different. The different of Ricci scalar described the different in spacetime that we talked about. Using this modified RS metric, we will localize the scalar and vector field. Thera are two ways that used to localized graviton. The first one is we took assumption that there is no interacting field, also known as minimal coupling principle. The second one said that there are interacting field between scalar or vector field with gravitation field; this principle also known as non-minimal coupling principle. Generally, both of two this ways gives us some conditions that should we take to make the certain field localized.<p align="justify"> |
