Dear Izzy, and all hadron spectroscopist,

I would also like to take this opportunity to remind you to submit a notification of your abstract submission to CSC. Information can be found on our wiki:

> The CLAS12 physics program is involved in the studies of the nucleon resonance spectrum and structure in electroproduction of a large variety of final states. With new CLAS12 data, we can investigate the electroproduction of the η and η’ mesons, which will provide a useful tool to study nucleon resonances N*. Due to the fact that both η and η’ have isospin I = 0 this provides an “isospin filter” that allows us to access nucleon resonances where I = ½. This work uses the 6.5 GeV data collected by CLAS12, with center of mass energy W ∼ 1-3 GeV, photon virtuality Q2 ∼ 0-6 GeV2, and luminosity 54 fb-1. The purpose of this work is to measure the differential cross section for η and η’ electroproduction. One of the steps necessary for this measurement is the determination of the bins and bin sizes for the kinematical parameters W, Q2, cosθ*, and ϕ*. This will require the development of programs that filter the data and the application of fiducial cuts to the remaining final states. After the data has been reduced to the relevant final states we will develop an automatic method to fit each individual kinematical bin and determine the goodness of said fit. This will enable us to extract the η and η’ signal in each bin to determine which bins can be used and which will need to be adjusted or rejected. Finally, to verify η and η’ detection, we will perform Monte Carlo simulations for comparison. This work is in contrast to the bulk of the current world database, which focuses on πN final states.
