ATLAS sets record precision on Higgs boson's mass

In the 11 years since its discovery at the Large Hadron Collider (LHC), the Higgs boson has become a central avenue for shedding light on the fundamental structure of the universe. Precise measurements of the properties of ...

An even closer look at the 'doubly magic' tin-100 nucleus

In a new paper published in Physical Review Letters, researchers working at CERN's ISOLDE facility describe how an upgrade to the ISOLTRAP experiment has allowed them to determine the energy necessary to bring the atomic ...

Experiments see first evidence of a rare Higgs boson decay

The discovery of the Higgs boson at CERN's Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently investigating the properties ...

CERN facility takes a solid tick forward towards a nuclear clock

Atomic clocks are the world's most precise timekeepers. Based on periodic transitions between two electronic states of an atom, they can track the passage of time with a precision as high as one part in a quintillion, meaning ...

Probing fundamental symmetries of nature with the Higgs boson

Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a universe of matter, with very little antimatter, remains a mystery. The excess of matter ...

New compact accelerator to help preserve heritage artworks

Beyond fundamental research, accelerators are well known for their contribution to the medical field, especially to cancer therapy. However, they can also be used in more unexpected ways, such as for the analysis of historical ...
