What kind of event is this? (1)
I had a question for any scientist: what kind of event is shown in this 4(?) ocv collision? (it's a few months since I saw it, but only just got around to posting this!)

Beautiful! This is clearly a "hadronic interaction". A standard particle (like a pion) has come from the collision and hit a bit of material (probably a silicon tracking detector sensor) in the detector, producing a secondary assortment of standard charged particles, which we see as displaced tracks coming from the displaced vertex. You can tell because the vertex is found exactly at a layer of tracking detector - the 3rd layer, in both the normal and slice views.
So is it scientifically relevant at all? 😃
