Matteo Rinaldi, Sergio Scopetta, Marco Traini, Vicente Vento
TL;DR
This paper uses a covariant Light-Front approach with AdS/QCD inputs to calculate double parton distribution functions of the pion, revealing new insights into its internal structure beyond single-parton distributions.
Contribution
It introduces a novel calculation of pion double parton distribution functions using a Poincaré covariant framework with soft-wall AdS/QCD input, providing new dynamical information.
Findings
Double parton distribution functions encode unique pion structure details.
Results demonstrate correlations not visible in single-parton distributions.
The approach offers a non-perturbative method to study hadron internal dynamics.
Abstract
Two-parton correlations in the pion are investigated in terms of double parton distribution functions. A Poincar\'e covariant Light-Front framework has been adopted. As non perturbative input, the pion wave function obtained within the so-called soft-wall AdS/QCD model has been used. Results show how novel dynamical information on the structure of the pion, not accessible through one-body parton distribution, are encoded in double parton distribution functions.
