M2-branes on M-folds | | Jacques Distler

9 Apr 2008 | | Abstract: | We argue that the moduli space for the Bagger-Lambert A_4 theory at level k
is(R^8 imes R^8)/D_{2k}, where D_{2k} is the dihedral group of order 4k. We
conjecture that the theory describes two M2-branes on a Z_{2k} ’’M-fold’’, in
which a geometrical action of Z_{2k} is combined with an action on the branes.
For k=1, this arises as the strong coupling limit of two D2-branes on an O2^-
orientifold, whose worldvolume theory is the maximally supersymmetric SO(4)
gauge theory. Finally, in an appropriate large-k limit we show that one
recovers compactified M-theory and the M2-branes reduce to D2-branes. | | Source: | arXiv, 0804.1256 | | Services: | Forum | Review | PDF | Favorites | |
