Making the MINERvA Measurement
What happens to make a masterclass
The masterclass starts, optionally, with preparation in the classroom. There a student learns some background ideas to make it easier to understand the masterclass measurement. It goes something like this:
We will concentration on the middle box inside the green field: the data analysis and what flows from it.
Here is the outline of the analysis tasks:
- Your masterclass leader will give you a data group and assignment within the group.
- Go to the Student Start Page and find your masterclass.
- Open your spreadsheet and find your place in it, corresponding to your data assignment.
- Next open your data group in the start page (letter next to your institute name) and then go to your data assignment. This opens the Arachne event display.
- For each "Entry" or "Gate" (both names are used) go from Slice to Slice until you find an event with a short proton track and a long muon track and no extraneous indications that could render the event too "noisy" to analyze.
- Choose the short proton track. Then copy the proton kinematics and paste them into the spreadsheet.
- Do the same for the long muon track.
- If you do not find a "good" Slice in the Gate, mark that Entry as "background" with a 1 in the appropriate column. Leave all else blank in the row.
- The spreadsheet will tally all the momenta measured in your masterclass and make some interesting histograms for you to discuss.
Here is the same thing in a video screencast:
Of course, there are more details. To learn these go the Library (link on sidebar) and then navigate to:the MINERvA page using the image map. If you want to really get into it, go to:

- Understanding MINERvA Masterclass Results
- MINERvA Masterclass Slides.
