$\eta$ electroproduction at high momentum transferred with CLAS

This analysis presents high quality angular distributions of the $p(\vec{e}, e'p)\eta$ reaction for full coupled-channel analysis purpose. The c.m. differential cross section ${d\sigma}/{d\Omega^*_{\eta}}$ will be extracted, and the unpolarized $\sigma_T$, $\sigma_L$, $\sigma_{LT}$, $\sigma_{TT}$ will be calculated. The measurement of the polarized longitudinal-transverse structure function $\sigma_{LT'}$ will provide new and useful information for untangling the $N^*$ states and to probe the interference between resonant and non-resonant processes. The CLAS spectrometer was used to detect the scattered electrons and final state protons, and the $\eta$'s were reconstructed by the missing mass technique. The angular distributions are obtained over the $4 \pi$ $c.m.$ solid angle. The beam polarization was $\sim 70\% $. \\ Preliminary data will be discussed.
