The apparent bagging of the Higgs boson — the long-sought “God” particle that endows all matter with mass, as well as its hypothesizers with a Nobel prize — topped Discover’s 2012 Year in Science list. But it wasn’t until 2013 that physicists at Europe’s Large Hadron Collider (LHC) confirmed that the elusive particle they’d nabbed was in fact a Higgs. 

To ascertain its identity, they analyzed 2.5 times more LHC data than they needed for the particle’s discovery. The results revealed that the particle discovered in 2012 has the quantum properties predicted for the Higgs: zero spin (a measure of angular momentum) and positive parity (a measure of how the particle’s mirror image behaves).
