Preliminary steps for UVA folks to get up and running:
Make sure you understand how the generate and use the Fun4Sim MonteCarlo setup. You don't need the reconstruction aspect but you need the generator-Geant chain to simulate different situations.
Look at the Generator options. There are three but Pythia and Legacy are the most relavant here.

After you learn about the different generators, use both to make some J/psi events generated from different vertex locations. Use the true vertex information to check that you generated what you though you generated by plotting the true vertex in each case. Also plot the true momentum distributions and plot the trueJ/psi peak from the true momentum components and make sure everything makes sense.
We are going to be moving both beam and target and looking at the following asymmetries so you should do a similar test for moving the target position. In this case you must use reconstruction to see anything.
Put the information to calculate phi in the CS frame.
Put the information on how to calculate asymmetries.
These tasks will need to be done for the online reconstruction and monitoring effort for SpinQuest.
- Level 1
- Vertex strip charts for single and dimuon
- Momentum Display
- Kinematic variables for the dimuon (xF, x1, x2,qT,cosphi, theta)
- Hit displays for every detector
- Event display for every reconstructed track
- DY and J/Psi L-R asymmetry
- DY and J/Psi Up-down asymmetry
You want both accumulated asymmetries and per spill, this tells you both the trend and how that compares to whats coming in.
