  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.
