An experimental program has been approved at the Thomas Jefferson National Accelerator Facility to measure the p(e, eK(+))Y reactions using the CLAS12 setup in Hall B. Data have been obtained using a 7.5 GeV electron beam, impinging upon a liquid-hydrogen target in the CLAS12 centre. The goal is to measure the Q(2) differential KY electroproduction cross section thus probing the Q(2) evolution of the N* resonance electrocouplings in the Q(2) range from 0.05GeV(2) to 3GeV(2): this will provide a crucial tool to investigate the possible hybrid nature of the N* resonances. Preliminary results from CLAS12 data are reported.

Abstract
An experimental program has been approved at the Thomas Jefferson National Accelerator Facility to measure the p(e, eK(+))Y reactions using the CLAS12 setup in Hall B. Data have been obtained using a 7.5 GeV electron beam, impinging upon a liquid-hydrogen target in the CLAS12 centre. The goal is to measure the Q(2) differential KY electroproduction cross section thus probing the Q(2) evolution of the N* resonance electrocouplings in the Q(2) range from 0.05GeV(2) to 3GeV(2): this will provide a crucial tool to investigate the possible hybrid nature of the N* resonances. Preliminary results from CLAS12 data are reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
