Who dunnit? 3
Here we have a display with a different colour scheme. The energy of the collision has rematerialised as many particles. Can you say what most of these particles must be? It will help to first check that you can recognise the different parts of the detector. The bright orange ring is the electron/photon detector (electromagnetic calorimeter), and outside it the dark gap is where the electromagnetic coil lies. So the outer bright blocks show energy deposited by protons and other hadrons.
