![]() ![]() Scientific curiosity applied to the Higgs boson shows us that. ![]() ![]() This work yields strong constraints on the Higgs boson’s decay width as well as evidence for the presence of off-shell contributions of the Higgs boson to the production rate of events with invariant masses above 220 GeV. The Higgs boson is an elementary particle relating to mass, a property without which the universe could not have been created. Now, writing in Nature Physics 6, the CMS Collaboration reports just such a measurement by examining the production rate of ZZ events with invariant masses far above the Higgs boson mass of approximately 125 GeV, referred to as off-shell, and comparing it with the on-shell case where the Higgs mass is close to its nominal value. Therefore, it is important to measure the width of the Higgs boson to constrain such possible contributions. Every character has been hand carved onto lino and hand printed with waterbased ink. It comes in two font formats OpenType-SVG bitmap and standard vector font. However, a substantial contribution to the Higgs boson’s decay width from modes with invisible or otherwise hard-to-detect particles cannot be excluded with existing data 3, 4, 5.

According to the standard model, a particle’s mass depends on how strongly it interacts with the Higgs field. Measurements of the products of these are consistent with standard model predictions 1, 2. The Higgs boson interacts with other particles as the standard model predicts. If there were a massive particle that interacts only with the Higgs boson but not with any other particle, its effects may be invisible in particle physics experiments except for changes to the Higgs boson’s production rates and decay branching fractions. The Higgs boson is a particle like no other: it interacts with other particles with strengths proportional to their masses. ![]()
