(19) But the Standard Model of particle physics – of which the Higgs boson is part and which describes fundamental particles and forces of nature – hides a terrifying secret: a theoretical composite particle that is so stable it can transform any other particle of matter into a copy of itself.
(20) On Monday, scientists at the Tevatron, which was shut down by the US government last year , fired a parting shot, releasing a fresh analysis that showed their strongest evidence yet for the Higgs boson .
