"The search is on for the Higgs boson, and it seems likely that soon we'll find this mysterious particle that creates matter in the universe. But what if we don't? In this week's "Ask a Physicist," we'll find out..." More>>

First Z bosons detected by CMS in heavy-ion collisions
Candidate Z Boson decaying to two electrons (two tallest red towers) in a lead-lead heavy ion collision at CMS. The other red and blue towers indicate energy deposits in CMS from other particles produced.
"Z bosons produced in collisions of heavy ions have been observed for the first time by the CMS experiment at CERN’s Large Hadron Collider (LHC). CMS observed 10 events containing a distinctive candidate Z boson reconstructed from a pair of electrons or a pair of muons (see figures 1 and 2 respectively), whose invariant mass is consistent with the Z boson mass..."
