Superpotentials and Membrane Instantons
We investigate nonperturbative effects in M -theory compactifications arising from wrapped membranes. In particular, we show that in d = 4,N = 1 compactifications along manifolds of G2 holonomy, membranes wrapped on rigid supersymmetric 3-cycles induce nonzero corrections to the superpotential. Thus, membrane instantons destabilize manyM -theory compactifications. Our computation shows that the...
متن کامل(Non-)BPS bound states and D-brane instantons
We study superpotential corrections due to decaying BPS D-brane instantons in four-dimensional N = 1 supersymmetric orientifold compactifications. The relevant objects are certain D-brane instantons which are not invariant under the orientifold projection. We show that they can yield superpotential contributions via a multi-instanton process on the BPS locus. This configuration decays in other ...
متن کاملMembrane instantons from mirror symmetry
We use mirror symmetry to determine and sum up a class of membrane instanton corrections to the hypermultiplet moduli space metric arising in Calabi–Yau threefold compactifications of type IIA strings. These corrections are mirror to the D1 and D(−1)–brane instantons on the IIB side and are given explicitly in terms of a single function in projective superspace. The corresponding four-dimension...
متن کاملMembrane and fivebrane instantons from quaternionic geometry
We determine the one-instanton corrections to the universal hypermultiplet moduli space coming both from Euclidean membranes and NS-fivebranes wrapping the cycles of a (rigid) Calabi-Yau threefold. These corrections are completely encoded by a single function characterizing a generic four-dimensional quaternion-Kähler metric without isometries. We give explicit solutions for this function descr...
متن کاملInstabilities in heterotic M-theory induced by open membrane instantons
We study the effective low energy supergravity of the strongly coupled heterotic string compactified on a Calabi-Yau 3-fold with generic E8 × E8 gauge bundle. We focus on the effective potential for the chiral scalars. The effective superpotential can be studied using the dual 11-dimensional M-theory background involving insertions of M5 branes along an interval. In such backgrounds, in some re...
