What <br class="">we have not included in our discussion in any detail is the fact that <br class="">the electron beam is highly spin polarized and that in the K+Lambda <br class="">channel we already measure the Lambda decay to proton-pi-, and thus we <br class="">automatically have the induced Lambda recoil polarization. With the <br class="">polarized electron beam we then can measure the polarization transfer <br class="">from the electron (virtual photon) to the Lambda.<br class=""><br class="">In the real photon case the BnGa analysis showed that the N(1900)3/2^+ <br class="">state was clearly identified by using the polarization transfer data <br class="">together with the other parts of the cross section. We will certainly do <br class="">the same in the future data analysis as well. However it would be nice <br class="">if we could demonstrate the sensitivity of these terms to resonance <br class="">excitation already for the proposal.<br class=""><br class=""> I am sure Daniel has those components already written down and we <br class="">could study the Legendre expansion of those terms in the simulation as <br class="">well.<br class=""><br class="">All the best,<br class="">Volker<br class=""><br class=""><br class=""><br class=""><br class=""><br class="">_______________________________________________<br class="">Hybrid_baryons mailing list<br class=""><a href="mailto:Hybrid_baryons@jlab.org" class="">Hybrid_baryons@jlab.org</a><br class="">https://mailman.jlab.org/mailman/listinfo/hybrid_baryons<br class="">_______________________________________________<br class="">Hybrid_baryons mailing list<br class="">Hybrid_baryons@jlab.org<br class="">https://mailman.jlab.org/mailman/listinfo/hybrid_baryons<br class=""></div></blockquote></div><br class=""><div apple-content-edited="true" class="">
