Bps Saturated Amplitudes and Non - Perturbative String
The study of the special F 4 and R4 in the effective action for the Spin(32)/Z2 and Type II strings sheds some light on D-brane calculus and on instanton contribution counting. The D-instanton case is discussed separately. Computations of non-perturbative contributions is still a difficult task. In (supersymmetric) Field theory a direct computation requires the construction of the measure of in...

Computations of non-perturbative contributions is still a difficult task. In (supersymmetric) Field theory a direct computation requires the construction of the measure of integration over vacua containing n-instantons, which is not yet available for every n. The use of dualities is still the main tool for getting the answer. In String theory the D-instantons contributions for the R4 were conje...
متن کاملPerturbative Gravity from QCD Amplitudes
We demonstrate that QCD gluon amplitudes can be used to construct a Lagrangian for gravity. This procedure makes use of perturbative ‘squaring’ relations between gravity and gauge theory that follow from string theory. We explicitly carry out the construction for up to five-point interactions and discuss a set of field variables in the Einstein-Hilbert Lagrangian for interpreting the Lagrangian...
متن کاملPerturbative BPS-algebras in superstring theory.
Perturbative BPS-algebras in superstring theory. ABSTRACT This paper investigates the algebraic structure that exists on perturbative BPS-states in the superstring, compactified on the product of a circle and a Calabi-Yau fourfold. This structure was defined in a recent article by Harvey and Moore. It shown that for a toroidal compactification this algebra is related to a generalized Kac-Moody ...
