Dear all,

Please read the abstract I submitted for HADRON23 and let me know if you 
have comments or corrections:

An experimental program has been approved at the Thomas Jefferson 
National Accelerator Facility to measure the (ep,e’K+)Y reactions using 
the CLAS12 setup in Hall B.
Data have been obtained using electron beams with energies of 6.5, 7.5, 
and 10.2 GeV, impinging upon a liquid hydrogen target in the CLAS12 
center. Scattered electrons have been detected in an
angle range of 2.5° to 4.5° by the Forward Tagger (FT) and at angles 
greater than 6° in the CLAS12 Forward Detector, allowing to measure the 
KY electro-production differential cross section and to
probe the Q2 evolution of the Nresonances electro-couplings in the Q2 
range from 0.05 GeV2 to 3 GeV2. The study of the Q2 dependence of the 
electro-couplings will provide a crucial tool to investigate the
possible hybrid nature of the N resonances. Experimental results for KY 
electroproduction will be reported and prospects for future studies will 
be discussed.

I apologize for not asking before.
Thank you in advance.
Best regards,

Lucilla
