Description
One of the central challenges in modern physics is to unravel hadronic structure, as the strongly coupled, non-perturbative nature of QCD at low energies makes it difficult to derive the observed properties of hadrons from their underlying quarks and gluons. The pion ($\pi$-meson) is the lightest quark system, and its properties are deeply linked to our understanding of how quarks are confined in hadronic matter. The pion form factor ($F_{\pi}$) is a key observable that can be accessed through the exclusive pion electro-production reaction $p(e,e' \pi^+)n$. The Pion-LT experiment was conducted to measure $F_{\pi}$ to high $Q^2$ across a broad kinematic range at the Thomas Jefferson National Accelerator Facility (JLab) in Newport News, Virginia, USA. This experiment aims to measure the separated longitudinal ($\sigma_L$) and transverse ($\sigma_T$) cross-sections using the unique Rosenbluth LT-separation technique to extract $F_{\pi}$ with high precision. In this talk, I will present preliminary results for LT-separated cross-sections at $Q^2 = 3.85$ GeV measured using the Rosenbluth technique, on behalf of the PionLT Collaboration.
