At 1.00 and 2.00 there are pairs of symmetrical white lines. Both pairs look quite similar. The one at 2.00 does not form a vertice.
Are these particle/antiparticle pairs? What are they? I can see the yellow data where they hit the calorimeter.
Should I infer an OCV at 2.00, even though the white lines don't cross?
What's going on here, please?
