Example electron pair Events

Events in which an electron-positron pair are produced are fairly easy to identify. We see a back-to-back pair of high momentum tracks pointing at high energy clusters of energy in the electromagnetic calorimeter.

Here are a couple of example events.

In the second example event the electrons strike the end-cap region of the detector.
