Self-tuning Solution of Cosmological Constant in RS-II Model and Goldstone Boson

Abstract

I give a review on the self-tuning solution of the cosmological constant in a 5D RS-II model using a three index antisymmetric tensor field $A_{MNP}$. The three index antisymmetric tensor field can be the fundamental one appearing in 11D supergravity. Also, the dual of its field strength $H_{MNPQ}$, being a massless scalar, may be interpreted as a Goldstone boson of some spontaneously broken global symmetry.
