Your conclusion should perform much the same role as the conclusion of an essay. You should succinctly explain what you've accomplished, and then anything else of interest which is illuminated by your results. You've got a lot of flexibility, here.

Explain your results. What is the invariant mass of the J/Psi? Which muon quality cut best reveals the mass of the J/Psi? Why?

Identify any noteworthy assumptions on which your conclusions depend.

Consider next steps, if any come to mind.

Questions for further exploration:

1. Visit the e-Lab data selection tool under the exploration tab. Choose J/Psi data (LHC 2010), choose event type "muons", and plot the invariant mass from both like sign and opposite signed muon pairs. Explain what must have been the muon quality filter applied to this set of 2000 events, the very same set you've used in this IPPW exercise. (Try this on your own, first. But here are some step-by-step hints if you need them.) You can write this question up as an investigation in a poster, if you have an argument you'de like to share.

2. Verify for some subset of the data that the histogram in the e-Lab looks or doesn't look much like the histogram produced in this exercise....use the "animate" function to add the same number of events as in your subset. (You can use a set of 100 events, or the total of all the events available at any moment. (Just "freeze" the total with a screen capture of the appropriate IPPW histogram, and hit the pause button in the e-Lab histogram tool animation controls.) Which IPPW histogram--of which muon quality cut--is the closest analogue to the e-Lab's opposite-signed invariant mass plot?

3. Explore the comments in the IPPW results spreadsheet. Explain one or more of the lines of code in the spreadsheet: what does it mean, what function does it perform? Explain which calculations that might have been performed one-at-a-time are instead automated by this code. Then write a set of directions--an algorithm--for automating some additional set of operations in this exercise that are currently performed one-at-a-time. Do you suppose that particle physicists automate those operations? Why might they?

Things to fix:

add instruction for zooming in to determine direction of curve...from the Z axis view
