This talk presents an exploration of meson structure studies using the Sullivan process, which provides valuable insights into the fundamental nature of hadrons within the framework of Quantum ChromoDynamics (QCD). The primary focus is on pion and kaon structures, offering unique opportunities for enhancing understanding of the emergent hadron mass-generating mechanism (EHM) and Generalized Parton Distributions (GPDs).
The KaonLT experiment, conducted in Hall C at Jefferson Lab (Jlab), employs a methodology comprising detector calibrations, efficiency studies, and offsets optimizations. These steps lead to the extraction of the kaon electroproduction cross section and the crucial separation of longitudinal and transverse components which, when warranted by the data, allow for kaon form factor extraction.
In addition to the Jlab efforts, ongoing research includes GEANT4 detector simulations to investigate the necessary requirements for measuring pion and kaon structure functions at the forthcoming Electron-Ion Collider (EIC). These investigations contribute significantly to constraining meson Parton Distribution Functions (PDFs) and validating the behavior of valence quark, sea quark, and gluon distributions.
