Five-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...
متن کاملFive-Brane Dynamics and Inflation in Heterotic M-Theory
Generic heterotic M-theory compactifications contain five-branes wrapping nonisolated genus zero or higher genus curves in a Calabi-Yau threefold. Non-perturbative superpotentials do not depend on moduli of such five-branes. We show that fluxes and non-perturbative effects can stabilize them in a non-supersymmetric AdS vacuum. We also show that these five-branes can be stabilized in a dS vacuum...
متن کاملFive–Brane BPS States in Heterotic M–Theory
We present explicit methods for computing the discriminant curves and the associated Kodaira type fiber degeneracies of elliptically fibered Calabi–Yau threefolds. These methods are applied to a specific three–family, SU(5) grand unified theory of particle physics within the context of Heterotic M–Theory. It is demonstrated that there is always a region of moduli space where a bulk space five–b...
متن کاملGauge Five Brane Moduli in Four Dimensional Heterotic M-theory
We present the first example of a Kähler potential for heterotic M-theory which includes gauge bundle moduli. These moduli describe the background gauge field configurations living on the orbifold fixed planes. We concentrate on the bundle moduli describing the size and SU(2) orientation of a gauge five brane a soliton which is primarily composed of these gauge fields. Our results are valid whe...
متن کاملDerivative 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.
