Tommaso Dorigo is an experimental particle physicist working on the CMS experiment at the Large Hadron Collider. His blog is an excellent resource if you’re interested in the LHC in particular and physics in general.
On Friday Tommaso posted this interesting piece about an unusually high-energy collision event in their early runs at the LHC’s newly increased power level:
The two jets have a combined invariant mass of 5.0 TeV, which is an extremely rare occurrence even for a 13 TeV collision - in fact, just one such event was collected so far, out of several trillion collisions. Such a feature can be produced by a very heavy particle (like, say, 5 TeV) which decays into a quark-antiquark pair. If such a thing does exist, that is. Or less excitingly, by a very rare scattering of two quarks or gluons in the two colliding objects.
I can’t wait to see if anything (or nothing for that matter) comes from the next round of experiments at LHC.
