Atomic Experiments for Dark Matter and Gravity Exploration

A workshop on “Atomic Experiments for Dark Matter and Gravity Exploration” was held at CERN on 22nd and 23rd of July, More than 130 participants met at CERN to review the landscape of cold atom experiments for exploring dark sector physics,…

First measurement of a long-lived meson-meson atom lifetime

In addition to the ordinary atoms, abnormal or exotic atoms serve as tools to study in detail the structure of atoms and their interactions. Different exotic atoms, consisting of other building blocks than electrons, protons and neutrons, have been…

Resolving a long-standing question at ISOLDE

Among the many pioneering results that have been published at ISOLDE was the discovery of odd-even staggering in the mean-square charge radius in neutron deficient Hg isotopes in the 1970s, as part of the RADOP experiment which measured the isotopic…

The MoEDAL Experiment at the Discovery Frontier

MoEDAL, the LHC’s newest experiment [1], that started official data taking in 2015, is different to other collider detectors. It is currently comprised of passive tracking, using plastic Nuclear Track Detectors (NTDs) and trapping sub-detectors that…

ALPHA-g sees its first antiparticles: does antimatter fall up or down?

The ALPHA collaboration working on antihydrogen at the Antiproton Decelerator (AD) in building 193 has successfully expanded their setup with new devices. The previous setup consisted of a positron accumulation device, accumulating positrons from a…

OSQAR experiment sheds light on a hidden sector of CERN’s scientific heritage

Particle physics is not only confined to the high energy frontier. There are unexplored territories at ultra-low energies, of sub-eV to eV, which are also very promising, such as for example in dark matter (DM) searches. The emblematic particle of…

Anti-nuclei in the cosmos and at the LHC

The ALICE collaboration has recently released several measurements on the production of anti-deuterons and anti-3He in proton-proton and Pb-Pb collisions at LHC energies. These results are not only interesting for the study of the hot QCD…

Cloud(y) climate studies at CERN

Continuous improvements to the CLOUD facility as well as to the instruments combined with the state of the art know-how available at CERN have enabled a steady increase in the measurement capabilities and resulted in numerous high impact…

ALPHA new results: pushing the limits in antimatter research

In a paper published this week in Nature, the ALPHA collaboration reports the most precise direct measurement of antimatter ever made, revealing the spectral structure of the antihydrogen atom in unprecedented accuracy. The result…

AMS looks at Cosmic Galactic Rays

The Alpha Magnetic Spectrometer (AMS) is a state-of-the-art particle physics experiment operating on the International Space Station (ISS) since May 2011. In the first 6 years of missions, AMS has detected over 100 billion cosmic ray (CR) particles…
