Testing the α ′ 3 term in the non - abelian open superstring effective action
نویسنده
چکیده
Recently, a proposal for the full non-abelian open superstring effective action through O(α′3) has been formulated in hep-th/0108169. We test this result by calculating the spectrum in the presence of constant magnetic background fields and by comparing the result to string theoretic predictions. The agreement is perfect. Other proposals for the superstring effective action through this order do not reproduce the spectrum correctly.

5-field terms in the open superstring effective action
Some time ago the bosonic and fermionic 4-field terms of the non-abelian low energy effective action of the open superstring were obtained, to all order in α. This was done at tree level by directly generalizing the abelian case, treated some time before, and considering the known expressions of all massless superstring 4-point amplitudes (at tree level). In the present work we obtain the boson...
متن کاملThe effective action for the 4-point functions in abelian open superstring theory
We construct the derivative corrections to the four-point vertices in the abelian open string effective action to all orders in α . The result is based on the structure of the string fourpoint function. Supersymmetry of these vertices is guaranteed by the supersymmetry of the F 4 term in the effective action. By this construction we establish the existence of an infinite number of supersymmetry...
متن کاملThe non - abelian open superstring effective action through order α ′ 3
Using the method developed in hep-th/0103015, we determine the non-abelian Born-Infeld action through O(α′3). We start from solutions to a Yang-Mills theory which define a stable holomorphic vector bundle. In D-brane context this corresponds to BPS configurations in the limit of small background fields. Subsequently we investigate its deformation away from this limit. Through O(α′2), a unique, ...
متن کاملAbelian Z-theory: NLSM amplitudes and α-corrections from the open string
In this paper we derive the tree-level S-matrix of the effective theory of Goldstone bosons known as the non-linear sigma model (NLSM) from string theory. This novel connection relies on a recent realization of tree-level open-superstring S-matrix predictions as a double copy of super-Yang-Mills theory with Z-theory — the collection of putative scalar effective field theories encoding all the α...
متن کاملSupersymmetric non-abelian Born-Infeld revisited
We determine the non-abelian Born-Infeld action, including fermions, as it results from the four-point tree-level open superstring scattering amplitudes at order α′2. We find that, after an appropriate field redefinition all terms at this order can be written as a symmetrised trace. We confront this action with the results that follow from kappa-symmetry and conclude that the recently proposed ...
