TL;DR

This paper uses light-front holography to predict pion properties, incorporating QCD-constrained dynamical spin effects to improve accuracy.

Contribution

It introduces a method to include higher twist dynamical spin effects in the pion holographic wavefunction constrained by QCD.

Demonstrates the importance of dynamical spin effects in holographic models.

Provides a framework for incorporating QCD constraints into light-front holography.

Abstract

Using light-front holography, we predict simultaneously the pion decay constant and the pion charge radius by taking into account (higher twist) dynamical spin effects whose relative importance is constrained by QCD.
