Photoproduction through Chern-Simons Term Induced Interactions in Holographic QCD

TL;DR

This paper uses holographic QCD models to compute interactions induced by the Chern-Simons term, analyzing their role in $f_1$ meson photoproduction and proposing a method to distinguish these effects experimentally.

Contribution

It provides the first detailed calculation of Chern-Simons term-induced couplings in holographic QCD and links these to observable polarization effects in meson photoproduction.

Findings

Derived vertex functions and couplings from holographic models.

Identified a polarization relation unique to Chern-Simons interactions.

Proposed experimental signatures to isolate these interactions.

Abstract

We employ both top-down and bottom-up holographic dual models of QCD to calculate vertex functions and couplings that are induced by the five dimensional Chern-Simons term. We use these couplings to study the photoproduction of $f_1$ mesons. The Chern-Simons-term-induced interaction leads to a simple relation between the polarization of the incoming photon and the final state $f_1$ meson which should allow a clear separation of this interaction from competing processes.
