Higgs10: inventing the future of Higgs research 10 Agosto, 2022
Higgs10: inventing the future of Higgs research In 1975, three CERN theorists, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos, undertook the first comprehensive study of the collider phenomenology of the Higgs boson. Almost 40 years later, it was discovered at the LHC. Now, ten years on, might we have such long-term foresight in anticipating […]
Mapping out the future of high-energy physics in the United States 9 Agosto, 2022
Mapping out the future of high-energy physics in the United States On 17 July 2022, hundreds of US high-energy physicists, along with colleagues from all over the world, gathered at the University of Washington in Seattle for a ten-day meeting to take one of the final steps in the latest US high-energy physics (HEP) community […]
Higgs10: Ten things we’ve learned about the Higgs boson in the past ten years 27 Julho, 2022
(Image: CERN) Higgs10: Ten things we’ve learned about the Higgs boson in the past ten years By: Monica Dunford& Andre David 19 July, 2022 · Voir en français In the seventh part of the Higgs10 series, we give an overview of ten years of Higgs boson research. Since its discovery in 2012, the Higgs […]
ATLAS measures joint polarisation of carriers of the weak force 13 Julho, 2022
ATLAS measures joint polarisation of carriers of the weak force In the Standard Model of particle physics, the Brout–Englert–Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mechanism, probes of other particles that have mass can also provide insight. For instance, the W […]
Higgs10: When spring 2012 turned to summer 7 Julho, 2022
(Image: CERN) Higgs10: When spring 2012 turned to summer By: Fabiola Gianotti& Joe Incandela 04 July, 2022 · Voir en français In the sixth part of the Higgs10 series, the ATLAS and CMS experiments announce the discovery on 4 July 2012 At the Higgs boson search update seminar on 13 December 2011, things were already […]
CMS measures rare particle decay with high precision 4 Julho, 2022
CMS measures rare particle decay with high precision At CERN’s Large Hadron Collider (LHC), studies of rare processes allow scientists to infer the presence of heavy particles, including undiscovered particles, that cannot be directly produced. Such particles are widely anticipated to exist beyond the Standard Model, and could help explain some of the enigmas of […]
LHCb discovers three new exotic particles 4 Julho, 2022
LHCb discovers three new exotic particles The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which includes a new type of tetraquark. The findings, presented today at a CERN seminar, add three new exotic members to the growing list […]
ATLAS and CMS release results of most comprehensive studies yet of Higgs boson’s properties 4 Julho, 2022
ATLAS and CMS release results of most comprehensive studies yet of Higgs boson’s properties Today, exactly ten years after announcing the discovery of the Higgs boson, the international ATLAS and CMS collaborations at the Large Hadron Collider (LHC) report the results of their most comprehensive studies yet of the properties of this unique particle. The […]
LHC Run 3: physics at record energy starts tomorrow 1 Julho, 2022
LHC Run 3: physics at record energy starts tomorrow A new period of data taking begins on Tuesday, 5 July for the experiments at the world’s most powerful particle accelerator, the Large Hadron Collider (LHC), after more than three years of upgrade and maintenance work. Beams have already been circulating in CERN’s accelerator complex since […]
The Higgs boson, ten years after its discovery 1 Julho, 2022
The Higgs boson, ten years after its discovery 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 […]
