Pion Elastic Form Factor in a Rather Broad Range of Momentum Transfers from Local-Duality QCD Sum Rule

TL;DR

This paper explores the pion elastic form factor across a broad range of momentum transfers using local-duality QCD sum rules, highlighting the method's relevance and potential for accurate predictions.

Contribution

It demonstrates the applicability of local-duality QCD sum rules to the pion elastic form factor over a wide momentum transfer range, offering new insights into non-perturbative QCD.

Findings

Local-duality sum rules effectively describe the pion form factor.

The approach provides reliable predictions across a broad momentum transfer range.

Revisiting sum rules enhances understanding of non-perturbative QCD effects.

Abstract

Revisiting, within QCD sum rules, the relevance of local duality for the pion elastic form factor gives rise to optimism.
