New ‘super light source’ should allow fascinating insights into atoms

‘Gamma Factory’ will enable not only breakthroughs in spectroscopy but also novel ways of testing fundamental symmetries of nature

24-Jul-2020 - The ‘Gamma Factory initiative’ – an international team of scientists – is currently exploring a novel research tool: They propose to develop a source of high-intensity gamma rays using the existing accelerator facilities at CERN. To do this, specialized ion beams will be circulated in the SPS and ...

Scientists discover long-sought Higgs decay

Detectors at the world's largest collider LHC at CERN prove Higgs decay into two b quarks

30-Aug-2018 - Scientists from the two major particle physics experiments ATLAS and CMS at CERN have observed the Higgs boson decaying into two b-quarks, they announced at a joint seminar at CERN today. According to theory, far more than half of all Higgs particles decay into these two quarks, but it is ...

Protons and antiprotons appear to be true mirror images

14-Aug-2015 - CPT invariance means that a system remains unchanged if three fundamental properties are reversed - C (charge), which distinguishes matter from antimatter, P (parity), which implies a 180 degree flip in space, and T (time). It is a central tenet of the standard model, and implies that antimatter ...

CERN’s LHCb experiment reports observation of exotic pentaquark particles

16-Jul-2015 - The LHCb experiment at CERN’s Large Hadron Collider has reported the discovery of a class of particles known as pentaquarks. The collaboration has submitted a paper reporting these findings to the journal Physical Review Letters. “The pentaquark is not just any new particle,” said LHCb ...

Observation of the 'charming socialites'

02-Jan-2014 - Protons and neutrons, the particles in an atomic nucleus, are made of smaller pieces called "quarks." Some types of quarks can form particles that exhibit surprising behaviors. Mark Mattson, Ph.D., assistant professor-research, and Paul Karchin, Ph.D., professor, from Wayne State University's ...

CERN experiments observe particle consistent with long-sought Higgs boson

05-Jul-2012 - At a seminar held at CERN as a curtain raiser to the year’s major particle physics conference, ICHEP2012 in Melbourne, the ATLAS and CMS experiments presented their latest preliminary results in the search for the long sought Higgs particle. Both experiments observe a new particle in the mass ...

Researchers from the University of Zurich discover new particle at CERN

30-Apr-2012 - Physicists from the University of Zurich have discovered a previously unknown particle composed of three quarks in the Large Hadron Collider (LHC) particle accelerator. A new baryon could thus be detected for the first time at the LHC. The baryon known as Xi_b^* confirms fundamental assumptions ...

First hint of the Higgs boson particle

Particle physicists at Mainz University are excited: 50 years after its prediction, the Higgs boson gradually takes shape

10-Jan-2012 - The answer to one of the most exciting questions in particle physics seems almost close enough to touch: Scientists at the Geneva research center CERN have observed first signs of the Higgs boson and now believe that they will soon be able to prove the existence of the elementary particle they ...

U of A-led experiment at CERN could rewrite laws of physics

26-Mar-2010 - An experiment led by a University of Alberta researcher, at the Large Hadron Collider (LHC) at CERN, could dramatically change our concepts of basic physics, revolutionize our understanding of the Universe and could eventually lead to technologies in future generations that right now only exist ...

Iowa State physicists beginning to see data from the Large Hadron Collider

11-Jan-2010 - Three Iowa State University physicists who took winter trips to the Large Hadron Collider for meetings and experimental work are starting to see real data from the planet's biggest science experiment. Finally. The multibillion-dollar collider made international news on Sept. 10, 2008, when it ...
