Please send comments to me. Thanks.<br><br>Best regards, Kyungseon<br><br>----------------------------------------------------------------------------------------------------------------------------------------------------<br>Title: The study of the electrogamatic N* transition form factors with<br>CLAS12 at Jefferson Lab<br><br>We will discuss the program to study the electromagnetic N* transition<br>form factors<br>with the CLAS12 detector and the energy upgraded 12 GeV<br>CEBAF beam at Jefferson Lab. The goal of this program is to explore<br>the evolution of the<br>active degrees of freedom in excited nucleon states from meson-baryon<br>dressing to dressed quark<br>contributions, and to learn how the strong interaction creates dressed<br>quark cores in various N* and how they emerge from QCD.<br>We plan to measure exclusive single-meson and double-pion<br>electroproduction cross sections off a proton target to study the<br>nucleon resonances.<br>Exclusive final states will be measured including the<br>identification of pi0 and eta mesons by measuring the two decay<br>photons as well as of charged multi-pions. From the proposed<br>measurements, we expect to obtain the electromagnetic transition form<br>factors for well established excited nucleon states in the unexplored<br>domain of Q2 from 5.0 to 10.0 GeV2. The close collaboration<br>experimentalists and theorist will allow us to provide high-precission data,<br>high-quality analyses, as well as state of the art model and QCD based<br>calculations.<br>We also review the current N* program with CLAS at Jefferson Lab as well.<br><br>-- <br>Kyungseon Joo Associate Professor of Physics<br>University of Connecticut<br>Storrs, CT 06269 <a href="http://www.phys.uconn.edu/~kjoo">http://www.phys.uconn.edu/~kjoo</a><br></div></blockquote></div><br></body></html>
