Here, I have embedded a pion pairs with a 100 MeV/c momentum difference into a Au+Be event at the pixel level.
These will be easy to pull apart, but note that it is clear even at this stage that the seperation efficiency will depend strongly on where you are in phase space.

For a bit more info on what is done, see the page showing the single embedded proton in this same event.

Also see the page that discusses track splitting even in this simple event!

Hey-- Why does this event look noisier with 2dh than with 1dh??!!
