Higgs running out of hiding places

New measurement of another particle’s mass confirms a final missing piece of physics’ puzzle is right where scientists think it is

Even as physicists in Europe close in on their most-wanted quarry — a particle known as the Higgs boson — scientists in Illinois are helping narrow the hunt. New measurements of a different particle, one called the W boson, confirm the Higgs is in the mass range that most physicists had thought.

Theory suggests that the Higgs particle must exist in order to imbue many other particles with mass. Experiments at the Large Hadron Collider, at the CERN laboratory near Geneva, have shown that the Hi...
