Instantons, Hypermultiplets and the Heterotic String
Hypermultiplet couplings in type IIA string theory on a Calabi-Yau space can be quantum corrected byD2-brane instantons wrapping special Lagrangian cycles. On the other hand, hypermultiplet couplings in the heterotic string on a K3 surface are corrected by world-sheet instantons wrapping curves. In a class of examples, we relate these two sets of instanton corrections. We first present an analo...
متن کاملUnoriented D-brane Instantons vs Heterotic worldsheet Instantons
We discuss Fermi interactions of four hyperini generated by “stringy” instantons in a Type I / Heterotic dual pair on T 4/Z2.
متن کاملInstantons and Solitons in Heterotic String Theory
This is a transcript of lectures given at the Sixth Jorge Andre Swieca Summer School in Theoretical Physics. The subject of these lectures is soliton solutions of string theory. We construct a class of exact conformal field theories possessing a spacetime soliton or instanton interpretation and present a preliminary discussion of their physical properties.
متن کاملInstantons, Assisted Inflation and Heterotic M-theory
We first investigate the attractor solution associated with Assisted Inflation in Heterotic M-Theory to see if it is stable. By perturbing the solutions we find a solitary stable fixed point with the general path through phase space dependent upon the Calabi-Yau data and the number of five-branes. We then go on to examine the effect of including non-perturbative corrections to the inflaton pote...
متن کاملHeterotic / Type II Triality and Instantons on K 3
A detailed understanding of instanton effects for half-BPS couplings is pursued in theories with 16 supersymmetries. In particular, we investigate the duality between heterotic string on T 4 and type IIA on K3 at the T /Z2 orbifold point, as well as their higher and lower dimensional versions. We present a remarkably clean quantitative test of the duality at the level of F 4 couplings, by compl...
