Does this method have advantage over dx/dy cuts?
P_perp has maximum ~75MeV/c for He3
- Evaluate P_perp cut with different W cuts
- Try much tighter cuts to test it
We need TOF
Can look at region of accidentals
We are seeing P_perp in the right units now - good
In the future, simulation could be used to look at inelastics
- For now, timing can be used on data
q vector direction is calculated from BB track reconstruction
- use energy of scattered electron as measured by BB
- what if you assume an energy that is equal to what you would have in the case of elastic scattering?
GMn is calculating dx and dy:
- "angles only" - purely elastic scattering (method 1)
- "4-vector" - use energy measured by BB (method 2)
Could investigate the different methods and the possible shift in q
How much of a shift compared to assuming no fermi motion?
Do we need a different approach to the background?
- A student should take the machinery and run it for GEn
We know momentum distribution of He3 from physics: where do we get these values? Reference? [1]
- Misak's code?
- Look at Freddy's thesis as well
Even if you have a good shell model description of wave function, when you measure, you miss fraction of nucleons that have a certain momentum
- We now associate with short range correlations - are we trying to get a distribution of momenta? Issue of missing strength?
- Page 5 of proposal [2]

What is the status of timing calibrations for GEn?
