Exotic atomic nucleus sheds light on the world of quarks 28 Novembro, 2023
Exotic atomic nucleus sheds light on the world of quarks Experiments at CERN and the Accelerator Laboratory in Jyväskylä, Finland, have revealed that the radius of an exotic nucleus of aluminium, 26mAl, is much larger than previously thought. The result, described in a paper just published in Physical Review Letters, sheds light on the effects […]
Bikash Sinha (1945 – 2023) 21 Novembro, 2023
Bikash Sinha (1945 – 2023) Bikash Sinha, influential Indian scientist and pioneer in quark–gluon plasma and the early Universe, passed away on 11 August at the age of 78. As one of the ALICE experiment’s early visionaries and architects, his impact on heavy-ion physics is unmistakable. Bikash Sinha was born on 16 June 1945 in […]
The CMS collaboration at CERN presents its latest search for new exotic particles 9 Novembro, 2023
The CMS collaboration at CERN presents its latest search for new exotic particles The CMS experiment has presented its first search for new physics using data from Run 3 of the Large Hadron Collider. The new study looks at the possibility of “dark photon” production in the decay of Higgs bosons in the detector. Dark […]
The November/December issue of the CERN Courier is out 2 Novembro, 2023
The November/December issue of the CERN Courier is out Welcome to a special issue of the Courier to celebrate the opening of CERN Science Gateway. In addition to lifting the lid on this new flagship facility for science education and outreach, we explore the broader issues surrounding education, communication and outreach in particle physics (p27). […]
ISOLDE sees shape shifting in gold nuclei 1 Novembro, 2023
ISOLDE sees shape shifting in gold nuclei A little like humans, the nuclei of atoms tend to shrink as they lose weight. But atomic nuclei are complex quantum systems formed from neutrons and protons that are themselves composite particles made of quarks. As such, their usually spherical or nearly spherical shapes do not always simply […]
Thick-skinned: Using heavy-ion collisions at the LHC, scientists determine the thickness of neutron “skin” in lead-208 nuclei 30 Outubro, 2023
Thick-skinned: Using heavy-ion collisions at the LHC, scientists determine the thickness of neutron “skin” in lead-208 nuclei Lead-208 has an intriguing nucleus. It is neutron rich, containing 82 protons and 126 neutrons. One of its more interesting properties is its structure: its centre is composed of both protons and neutrons, but at its edge, there […]
Symposium: Celebrating electroweak milestones | 31 October 10 Outubro, 2023
Symposium: Celebrating electroweak milestones | 31 October On 31 October 2023, CERN Science Gateway will host its first scientific event in the new Sergio Marchionne Auditorium. Celebrating 50 years since Gargamelle discovered neutral currents and 40 years since UA1 and UA2 discovered the W and Z bosons, the symposium offers a full-day programme of past […]
ATLAS and CMS unite to weigh in on the top quark 9 Outubro, 2023
ATLAS and CMS unite to weigh in on the top quark Among the known fundamental particles of the Universe, the top quark claims the heavyweight title, with a mass 184 times that of the proton. Measuring its precise value – along with that of the Higgs boson – provides crucial information about the theoretical underpinnings of […]
In search of supersymmetric dark matter 9 Outubro, 2023
In search of supersymmetric dark matter If new particles are out there, the Large Hadron Collider (LHC) is the ideal place to search for them. The theory of supersymmetry suggests that a whole new family of partner particles exists for each of the known fundamental particles. While this might seem extravagant, these partner particles could […]
ALPHA experiment at CERN observes the influence of gravity on antimatter 25 Setembro, 2023
ALPHA experiment at CERN observes the influence of gravity on antimatter Isaac Newton's historic work on gravity was apparently inspired by watching an apple fall to the ground from a tree. But what about an “anti-apple” made of antimatter, would it fall in the same way if it existed? According to Albert Einstein’s much-tested theory […]
