Higgs10: Three-quarters of the way there 25 Maio, 2022
Higgs10: Three-quarters of the way there 4 July 2012 wasn’t the first time physicists had packed themselves into the CERN auditorium to witness the discovery of a new elementary particle. To rapturous applause on 20 January 1983, Carlo Rubbia, spokesperson of the UA1 experiment at the Spp-barS collider, presented six candidate events for the W […]

At Gargamelle with Paul Musset (Image: CERN) 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 At the dawn of the 1970s, the idea of a massive scalar boson as the keystone of a unified theoretical model of […]
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: The Higgs boson and the rise of the Standard Model of Particle Physics in the 1970s 10 Maio, 2022
Higgs10: The Higgs boson and the rise of the Standard Model of Particle Physics in the 1970s At the dawn of the 1970s, the idea of a massive scalar boson as the keystone of a unified theoretical model of the weak and electromagnetic interactions had yet to become anchored in a field that was still […]
A boson is born 9 Maio, 2022
A graphic artistic view of the Brout-Englert-Higgs Field (Image: CERN) 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 an end […]
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 […]
Higgs10: A boson is born 28 Abril, 2022
Higgs10: A boson is born On 4 July 2012, half a century’s wait came to an end as the ATLAS and CMS experiments announced the discovery of the Higgs boson. Celebrate 10 years since this extraordinary achievement by learning more about the history that led up to it, the next steps in understanding the mysterious particle, and CERN’s role […]
CMS measures the mass of the top quark with unparalleled accuracy 19 Abril, 2022
CMS measures the mass of the top quark with unparalleled accuracy The CMS collaboration at the Large Hadron Collider (LHC) has performed the most accurate ever measurement of the mass of the top quark – the heaviest known elementary particle. The latest CMS result estimates the value of the top-quark mass with an accuracy of […]
LHCb reveals secret of antimatter creation in cosmic collisions 6 Abril, 2022
LHCb reveals secret of antimatter creation in cosmic collisions At the Quark Matter conference today and at the recent Rencontres de Moriond conference, the LHCb collaboration presented an analysis of particle collisions at the Large Hadron Collider (LHC) that may help determine whether or not any antimatter seen by experiments in space originates from the […]
