We calculate the extremal higher dimensional effective actions of fundamental brane-antibrane systems elegantly presented in the theoretical framework of advanced membrane theory constructions. Detailed study of brane-antibrane systems reveals when brane separation is smaller than the superstring length scale, spectrum of this system has different tachyonic modes and interaction regimes in the moduli superspace. The higher dimensional effective actions should then include these modes because they are the most important ones which rule the extremal dynamics of the fundamental brane systems. In this regard, it has been shown that an effec- tive action of Born-Infeld type proposed in the current literature can capture many properties of the decay of non-BPS Dp-branes in superstring and membrane theory. The effective actions of brane-antibrane systems in Types IIA and IIB superstring theories should be given by some extension of the DBI action and the WZ terms which include the tachyon field configurations. The DBI part may be given by the projection of the effective action of two non-BPS Dp-branes in Type IIB theory. We are interested in this paper in the appearance of tachyon, gauge field and the RR field in these extremal higher dimensional actions. Using the consistency of the present constructions, we have also found the first higher derivative corrections to the exceptional part of the extremal effective actions with brane-antibrane systems.
