TL;DR
This paper derives a fundamental light-front wave function for the pion that accurately reproduces its valence parton distribution and electromagnetic form factor, aligning with experimental data.
Contribution
It introduces a lowest-order $qar q$ valence light-front wave function for the pion with specific angular momentum components, matching key experimental observables.
Findings
Wave function reproduces valence parton distribution
Wave function matches electromagnetic form factor data
Provides a theoretical basis for pion structure modeling
Abstract
We derive the lowest-order valence light-front wave function for the pion with Lz=0 and |Lz|=1, which reproduces its valence parton distribution and the electromagnetic form factor consistent with data.
