Description
An experimental program has been approved at the Thomas Jefferson National Accelerator Facility to study exclusive (KY) electroproduction with CLAS12 in order to search for new excited baryon states in the mass range ($W \simeq 1.8-3.0\text{ GeV}$). Two dedicated data-taking campaigns were carried out in 2018 and 2024. Although the 2018 dataset has limited statistics, it demonstrated excellent data quality and allowed for two publications: 2024 data will provides improved statistics and momentum resolution.
In this talk I will present preliminary results from the ($(ep,e'K^+)Y^*$) channel, with emphasis on the first steps of a beam–spin asymmetry (BSA) analysis using a longitudinally polarized electron beam and an unpolarized target.
