Higgs Boson Found

Higgs Boson
Event display of a H -> 2e2mu candidate event with m(4l) = 122.6 (123.9) GeV without (with) Z mass constraint. The masses of the lepton pairs are 87.9 GeV and 19.6 GeV. The event was recorded by ATLAS on 18-Jun-2012, 11:07:47 CEST in run number 205113 as event number 12611816. Muon tracks are colored red, electron tracks and clusters in the LAr calorimeter are colored green. The larger inset shows a zoom into the tracking detector. The smaller inset shows a zoom into the vertex region, indicating that the 4 leptons originate from the same primary vertex. © 2012 CERN

It’s quite possible (five sigma likely to be exact) that the above image is documentation of perhaps the greatest physics achievement in our lifetime, the observation of Higgs boson. The Daily Mail quite nicely summarized today:

The discovery fills in the last gap in the ‘standard model’ of physics – proving Einstein right, and possibly leading to new technologies built on our understanding of the particle.

Glad they didn’t wait for me to get started on this.

What Happens If You Put Your Hand In The LHC

Large Hadron Collider Cutaway Crossection

Large Hadron Collider Cutaway Crossection

Ever wonder what would happen if you put your hand or other body part in the Large Hadron Collider and the scientists turned it on? Well nobody actually knows, and it seems none of the scientists really want to find out. Their analysis of the question however is quite interesting.
