Looking at V0 reconstruction with the ALICE detector

Install the ALICE MasterClass executable here:

https://alice-masterclass.web.cern.ch/MasterClassInstallation.html

Note that you do not need to download ROOT, just the executable.  This is a large executable so please budget time for its download.

Read through the instructions here.

Run the executable.  Select the "Strange Particles" master class and then the "p-p events".  Then click start. 

For the data set, select "Demo Set." Under "Display", select tracks, V0s, Cascades, and Axes.  Rotate the display and make sure that you can identify the V0s.  You can turn things on and off to highlight different parts.  The first three events show V0s and the last one shows a cascade.

Now analyze "data set 1" instead of the demo set.  For each event, identify the V0, classify it, as the correct particle, and add it to the histograms by clicking submit.
