Gravitational Radiation from Travelling Waves on D-Strings

TL;DR

This paper constructs supersymmetric boundary states for fractional D-strings with traveling waves on a specific orbifold and calculates the gravitational radiation emitted between two such D-strings with antiparallel traveling waves.

Contribution

It introduces a method to model supersymmetric fractional D-strings with traveling waves and computes the resulting gravitational radiation in a complex orbifold setting.

Findings

Boundary states preserving supersymmetry are constructed.

Gravitational radiation between D-strings with antiparallel waves is calculated.

Results contribute to understanding D-string interactions and gravitational wave emission.

Abstract

Boundary states that preserve supersymmetry are constructed for fractional D-strings with travelling waves on a ${\bf C}^3/ {{\bf Z}_2\times {\bf Z}_2}$ orbifold. The gravitational radiation emitted between two D-strings with antiparallel travelling waves is calculated.
