Bjorn O. Lange
TL;DR
This paper introduces a novel dual space representation of the B-meson light-cone distribution amplitude, simplifying renormalization and providing insights into its perturbative and non-perturbative features.
Contribution
It proposes the dual LCDA based on eigenfunctions of the anomalous dimension kernel, reducing mixing under renormalization compared to traditional methods.
Findings
Dual LCDA simplifies renormalization group evolution.
Different dual momenta regions exhibit distinct perturbative and non-perturbative behaviors.
The approach offers new analytical tools for studying B-meson structure.
Abstract
We describe a representation of the leading B-meson light-cone distribution amplitude in heavy-quark effective theory based on the eigenfunctions of its anomalous dimension kernel. In this representation (called the dual LCDA) different dual momenta no longer mix under renormalization. We discuss the perturbative and non-perturbative nature of different regions in this space.
