The pion in holographic light-front QCD

TL;DR

This paper demonstrates that the pion's physical properties, such as radius and form factors, can be accurately predicted using light-front holographic QCD with a universal scale when dynamical spin effects are included.

Contribution

The study introduces a unified approach in holographic QCD that accounts for dynamical spin effects to predict pion properties accurately.

Findings

Accurate prediction of pion radius and decay constant.

Successful modeling of electromagnetic and transition form factors.

Validation of a universal AdS/QCD mass scale.

Abstract

We report that the pion radius, decay constant, EM and transition form factors can simultaneously and accurately be predicted in light-front holographic QCD with a universal AdS/QCD mass scale, provided dynamical spin effects are taken into account.
