On the absence of reflection in AdS4/CFT3

TL;DR

This paper discusses the reflectionless scattering in AdS4/CFT3, attributing it to local conserved charges that differentiate particle types, providing insights into integrability features of the model.

Contribution

It offers a theoretical explanation for the reflectionless property in AdS4/CFT3 scattering based on conserved charges, extending previous understanding of integrability.

Findings

Reflectionless scattering is linked to local conserved charges.

Different charges act distinctly on solitons and antisolitons.

Supports the integrability of the AdS4/CFT3 model.

Abstract

A noteworthy feature of the S-matrix which has been proposed for AdS4/CFT3 is that the scattering of an A-particle ("soliton") with a B-particle ("antisoliton") is reflectionless. We argue, following Zamolodchikov, that the absence of reflection is a result of the existence of certain local conserved charges which act differently on the two types of particles.
