# Hadronic Form Factors: Combining QCD Calculations with Analyticity

## TL;DR

This paper reviews the use of QCD light-cone sum rules to calculate pseudoscalar meson form factors, integrating soft and hard contributions and leveraging analyticity to extend the momentum transfer range.

## Contribution

It introduces a method combining QCD calculations with analyticity to improve the analysis of meson form factors across wider momentum regions.

## Key findings

- Successful application of light-cone sum rules to pseudoscalar meson form factors
- Enhanced momentum transfer range through analyticity integration
- Comprehensive account of soft and hard QCD contributions

## Abstract

I discuss recent applications of QCD light-cone sum rules to various form factors of pseudoscalar mesons. In this approach both soft and hard contributions to the form factors are taken into account. Combining QCD calculation with the analyticity of the form factors, one enlarges the region of accessible momentum transfers.
