Searching for matter–antimatter asymmetry with the Higgs boson 22 Junho, 2022
Searching for matter–antimatter asymmetry with the Higgs boson Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter in the present-day universe even though both forms of matter should have been created in […]
CMS on the lookout for new physics 17 Junho, 2022
CMS on the lookout for new physics With Run 3 of the LHC just around the corner, the LHC experiments are still publishing new results based on the previous runs’ data. Despite no new discoveries being announced, small deviations from expectations are appearing in a small number of analyses. At the current level these deviations […]
Higgs10: The dramatic last year of CERN’s flagship LEP collider 8 Junho, 2022
The LHC will be built inside the same tunnel as an existing accelerator, the Large Electron Positron (LEP) collider which came on stream in 1989. LEP will be removed from the tunnel at the end of this year to make way for the LHC. Here technicians make delicate adjustments to one of LEPs thousands of […]
Higgs10: The dramatic last year of CERN’s flagship LEP collider 31 Maio, 2022
Higgs10: The dramatic last year of CERN’s flagship LEP collider The year 2000 was set to be the last year of running for CERN’s Large Electron–Positron (LEP) collider, and it ended in dramatic fashion. Luciano Maiani was Director-General and Roger Cashmore Research Director as the new millennium dawned. Roger Cashmore : The final year of […]
Higgs10: Three-quarters of the way there 31 Maio, 2022
Higgs10 Bulletin article - 3 (Image: CERN) Higgs10: Three-quarters of the way there By: Matthew Chalmers 25 May, 2022 · Voir en français In the third part of the Higgs10 series, we see how the direct discovery of the W and Z bosons at the SppS in 1983 provided solid experimental support for the existence […]
Higgs10: The Higgs boson and the rise of the Standard Model of Particle Physics in the 1970s 16 Maio, 2022
At Gargamelle with Paul Musset (Image: CERN) Higgs10: The Higgs boson and the rise of the Standard Model of Particle Physics in the 1970s By: John Ellis 10 May, 2022 · Voir en français In part two of the Higgs10 series, we see how breakthroughs in the 1970s helped the Brout–Englert–Higgs (BEH) field and its […]
ALICE makes first direct observation of a fundamental effect in particle physics 16 Maio, 2022
ALICE makes first direct observation of a fundamental effect in particle physics The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect – a fundamental feature of the theory of the strong force that binds quarks and gluons together into protons, neutrons and, ultimately, all atomic […]
CLOUD discovers new way by which aerosols rapidly form and grow at high altitude 13 Maio, 2022
CLOUD discovers new way by which aerosols rapidly form and grow at high altitude Aerosol particles can form and grow in Earth’s upper troposphere in an unexpected way, reports the CLOUD collaboration in a paper1 published today in Nature. The new mechanism may represent a major source of cloud and ice seed particles in areas […]
Higgs10: A boson is born 9 Maio, 2022
A graphic artistic view of the Brout-Englert-Higgs Field (Image: CERN) Higgs10: A boson is born By: Matthew Chalmers 28 April, 2022 · Voir en français In the first part of the Higgs10 series, we look at the how the Higgs boson came to be On 4 July 2012, half a century’s wait came to […]
CMS tries out the seesaw 4 Maio, 2022
CMS tries out the seesaw The CMS collaboration at the Large Hadron Collider (LHC) has carried out a new test on a model that was developed to explain the tiny mass of neutrinos, electrically neutral particles that change type as they travel through space. In the Standard Model of particle physics, the particles that cannot […]
