Modern theoretical particle physics models are both elegant and powerful. These theories can predict precision measurements of fundamental interactions over many orders of magnitude, but they are intrinsically flawed. A major problem arises when one considers a seemingly trivial concept: the masses of elementary particles. Most particle physicists believe this issue is addressed by an electroweak symmetry breaking model known as the Higgs mechanism, which predicts the existence of a new (and unobserved!) particle, the Higgs boson. For nearly 50 years physicists have sought the Higgs boson, searching in dark corners for signs of its existence. After following trails of clues, the collider experiments at the Fermilab Tevatron and the CERN Large Hadron Collider may together be seeing the first tangible hints of the Higgs boson. This presentation will discuss the basic motivations for the Higgs mechanism and the exciting, new results on Higgs searches from the Tevatron and the LHC.
