The Higgs boson - CERN
To confirm if it really was the Higgs boson, physicists needed to check its “spin” – the Higgs boson is the only particle to have a spin of zero. By examining two and a half times more data, they concluded in March 2013 that, indeed, some kind of Higgs boson had been discovered.
What's so special about the Higgs boson? - CERN
The Higgs boson is that particle, and its discovery in 2012 confirmed the BEH mechanism and the Higgs field, allowing researchers to probe ever further in their understanding of matter. Measuring the properties of the Higgs boson in detail is crucial to exploring many outstanding mysteries in particle physics and cosmology, from the wild ...
How did we discover the Higgs boson? - CERN
The problem is that the particles that the Higgs decays into are the same kinds of particles that are copiously produced in particle collisions. Simply seeing a pair of photons (one of the final states from the Higgs boson decay) is hardly any indication that the Higgs boson exists and is being produced in the experiment.
The Higgs boson: Revealing nature’s secrets - CERN
2020年7月4日 · The Higgs boson holds the key to our understanding of nature beyond what is shown by the Standard Model. ATLAS and CMS are, for example, looking for so-called “invisible decays” of the Higgs boson, in which it transforms into particles that the detectors cannot observe. These invisible particles might be manifestations of dark matter. And ...
How does the Higgs boson impact everyday life? - CERN
The Higgs boson itself is part of the answer to why we – and everything we interact with – have mass. The Higgs boson underpins the whole Standard Model like a jigsaw piece, spurring on our curiosity and creating a more accurate picture of the universe around us. Since the beginning of humanity, curiosity has fuelled the advancement of science.
The basics of the Higgs boson - CERN
2013年5月16日 · The Higgs boson is one of two types of fundamental particles, and it’s a particular game-changer in the field of particle physics, proving how particles gain mass. Using the Socratic method, CERN physicists Dave Barney and Steve Goldfarb explain the exciting implications of the Higgs boson.
What’s next for Higgs boson research? - CERN
The Higgs boson could then decay into pairs of such particles, that would then leave the detector without interacting, which is the subject of searches for so-called “invisible Higgs decays”. The interaction between the Higgs boson and the top quark …
The Higgs boson, ten years after its discovery - CERN
Geneva, 4 July 2022. Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard Model of particle physics. The discovery was a landmark in the history of science and captured the world’s attention. One year later it …
The Higgs boson: What makes it special? - CERN
2020年5月4日 · In 1964, two papers – one by Robert Brout and François Englert, the other by Peter Higgs – purported to have a solution: a new mechanism that would break the electroweak symmetry. The Brout-Englert-Higgs mechanism introduced a new quantum field that today we call the Higgs field, whose quantum manifestation is the Higgs boson.
CMS releases Higgs boson discovery data to the public
2024年4月16日 · CMS event display of a candidate Higgs boson decaying into two photons, one of the two decay channels that were key to the discovery of the particle. (Image: CERN) As part of its continued commitment to making its science fully open, the CMS collaboration has just publicly released, in electronic format, the combination of CMS measurements that contributed to …
