[clas12_rgk] APS Meeting abstract

[Viktor Mokeev]

Hi Izzy,

Thank you for the abstract on important topic in the N* program with the CLAS12!

I propose you change:

in the study of meson spectroscopy in electroproduction of a large variety of final states.---->

in the studies of the nucleon resonance spectrum and structure in electroproduction of a large variety of final states.

Channels you are studying  are of particular importance in order to further clarify the information on gvpN* electrocouplins of nucleon resonances at 1.0 < Q^2< 5.0 GeV^2. Combined studies on eta/eta_prime photo-/electroproduction data has a potential to reveal/confirm
 new baryon states, as in a case of pi^+pi^-p photo-/electroproduction combined analysis which revealed the presence of new N'(1720)3/2+ resonance recently published in Phys. Lett B.

Best Regards,
                                 Victor

Dear all,

Below is my abstract for the spring APS meeting. Thank you to Bill, Igor, and Volker for their contributions. I would appreciate any other comments and suggestions.

Study of η and η’ Electroproduction with JLab's CLAS12 Detector

-abstract-

The CLAS12 physics program is involved in the study of meson spectroscopy 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 complementary 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. One of the primary steps for this work is the identification of η and η’ in the 6.5 GeV data collected by Run Group K (center of mass energy W ∼ 1-3 GeV, photon virtuality Q2 ∼ 0-6 GeV2, and luminosity 54 fb-1) via their decays into  γ\ga’s and π’s. This will require the use of Monte Carlo simulations and the development of programs that filter the data for the relevant final states. Some channels pose unique issues of particle identification and complex combinatorics. To verify the detection of η and η’, mass, momentum, angle and other plots will need to be produced and compared to MC simulations. This work is in contrast to the bulk of the current world database, which focuses on πN final states.

All the best,

Izzy
