Geometric counter-vertex for open string scattering on D-branes

TL;DR

This paper explores the extension of a conjecture that quantum effects of open strings on D-branes generate the D-brane geometry, by analyzing two-loop corrections to the counter-vertex operator.

Contribution

It extends previous one-loop analyses to two-loop order, providing deeper insights into the quantum generation of D-brane geometry from open string effects.

Findings

Confirmation of the two-loop extension of the counter-vertex conjecture

Deeper understanding of quantum effects in open string interactions

Progress towards a complete quantum description of D-brane geometry

Abstract

In arXiv:0801.0218 [hep-th] it was conjectured that quantum effects of open strings moving on D-branes generate the D-brane geometry through a counter-vertex operator. The conjecture has been checked at one-loop in arXiv:0806.3330 [hep-th]. Here we discuss the two-loop extension.
