Polarization Observables T and F in \(\pi ^0\) Photoproduction Off the Proton with CLAS g9 Experiment

Pion photoproduction in the \(\gamma p \rightarrow \pi ^0 p\) reaction has been measured in the FROST experiment at the Thomas Jefferson National Accelerator Facility. In this experiment, circularly polarized photons with energies up to 3.082 GeV impinged on a transversely polarized frozen-spin target. Final-state protons were detected in the CEBAF Large Acceptance Spectrometer. Preliminary results of the polarization observables T and F have been extracted. The data generally agree with predictions of present partial-wave analyses, but also show marked differences. The data will constrain further partial wave analyses and improve the extraction of proton resonance properties.
