Derivative F-Terms from Heterotic M-Theory Five-brane Instantons
We study non-perturbative effects due to a heterotic M-theory five-brane wrapped on Calabi-Yau threefold. We show that such instantons contribute to derivative Fterms described recently by Beasley and Witten rather than to the superpotential.
متن کاملD-brane Instantons in Type II String Theory
We review recent progress in determining the effects of D-brane instantons inN = 1 supersymmetric compactifications of Type II string theory to four dimensions. We describe the abstract D-brane instanton calculus for holomorphic couplings such as the superpotential, the gauge kinetic function and higher fermionic F-terms. This includes a discussion of multi-instanton effects and the implication...
متن کاملFive-brane Effective Action in M -theory
On the world-volume of an M -theory five-brane propagates a two-form with selfdual field strength. As this field is non-Lagrangian, there is no obvious framework for determining its partition function. An analogous problem exists in Type IIB superstring theory for the self-dual five-form. The resolution of these problems and definition of the partition function is explained. A more complete ana...
متن کاملThe M Theory Five - Brane 1
BPS saturated p-branes play an important role in recent progress in understanding superstring theory and M theory. One approach to understanding the dynamics of p-branes is to formulate an effective (p+1)-dimensional world-volume theory. The construction of such brane actions involves a number of interesting issues. One such issue is how to formulate the action for theories that contain chiral ...
متن کاملFive-Brane Superpotentials in Heterotic M-theory
The open supermembrane contribution to the non-perturbative superpotential of bulk space five-branes in heterotic M -theory is presented. We explicitly compute the superpotential for the modulus associated with the separation of a bulk five-brane from an end-of-the-world three-brane. The gauge and κ-invariant boundary strings of such open supermembranes are given and the role of the holomorphic...
