Description
An experimental program has been approved at the Thomas Jefferson National Accelerator Facility to measure the KY electroproduction reactions to search for new excited baryon states in the mass range from 1.8 GeV to 3 GeV with CLAS12. As part of this project two data taking campaigns took place in 2018 and 2024: despite its limited statistics the first run has proved to be of high quality allowing a first publication, while the second run presents improved statistics and momentum resolution and will provide new tools for future studies. Preliminary results, including first steps for a Beam Spin Asimmetry study employing (ep,e’K+)Y* channel, are reported in this contribution, with the ultimate goal of measuring the KY electroproduction differential cross section and to probe the Q^2 evolution of the nucleon resonances electro-couplings in the low Q^2 range.
