Is this pure random chance or something more?

Hi @ptd, mesons can decay into pairs of muons. Through a quick search, I found an article titled First measurement of Upsilon production at 7 TeV at the LHC which I found interesting. There is also this article:
Search for rare decay of neutral B mesons to two muons.
I think it is #weird, however, that there are four muons in this object. Also, a high-energy particle track appears next to these two muons, and another track is seen exiting at an odd angle.
if they were all headed in the same beam direction it could be a fairly rare ZZ -> muon/antimuon, muon/antimuon event (suggesting a Higgs event if the mass is right). The bent green lines and somewhat misshapen "physics object markers" could just mean the tracks go into the detector endcaps rather than the barrel, but it could also indicate a false positive. There is also a 5th muon marker about 1 o'clock, but most of the energy seems to be in the nearly #diametric muon tracks
