3He(e,e'd) Analysis

Comparison of the Proton Asymmetries:

I have rotated my measured proton asymmetries (HRSL = 14.5deg) and compared them with predictions from Golak for 2BBU. The results do not agree well. I believe this is due to differences in Q2. Theory was calculated for Q**2 = 0.39, while measurements were made at Q**2=0.3 (GeV/c)**2. Asymmetry changes quickly with the Q**2.

3BBU Results and PWIA interpretation

PWIA interpretation does not hold water for 3BBU. See MAINZ results!

Non zero asymmetry is caused by the FSI and is not a result of S' contribution.

Mainz Results for (e,e'p):

Achenbach et al. EPJ (2008)

I would like to compare my results with these measurements. We are both having very similar kinematics conditions. I need to run MCEEP simulation to estimate the 2BBU contribution inside the 3BBU.

New Definition of the Missing Energy (ExEn):

Until now I considered a missing energy (Excessive Energy) as an energy of everything that is not detected - Deuteron mass. Now I will use MAIZ definition which is omega-kinetic energy of all particles, assuming 2BBU. I expect only minor changes in the results since pmiss approx. 0.1GeV/c
