Derivative Corrections from Noncommutativity

TL;DR

This paper demonstrates that noncommutativity can be used to determine an infinite subset of higher-derivative alpha' corrections to open-string actions, aligning with explicit calculations at lowest order.

Contribution

It introduces a method to derive higher-derivative corrections from noncommutativity, extending previous explicit computations.

Findings

Agreement with explicit lowest-order alpha' corrections

Infinite subset of corrections can be predicted using noncommutativity

Method bridges noncommutative and commutative string theories

Abstract

We show that an infinite subset of the higher-derivative alpha' corrections to the DBI and Chern-Simons actions of ordinary commutative open-string theory can be determined using noncommutativity. Our predictions are compared to some lowest order alpha' corrections that have been computed explicitly by Wyllard (hep-th/0008125), and shown to agree.
