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…

BabyMIND records first muon tracks

Assembled as part of project NP05 at the CERN Neutrino Platform, the Baby MIND muon spectrometer has been recording its first muon tracks from neutrino interactions at J-PARC since 10th March. Baby MIND is designed to determine the momentum and…

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…

First positrons for GBAR

At the CERN Antimatter Factory, antihydrogen atoms are produced routinely by merging antiprotons and positrons. In order to control this process, it is necessary to reduce the energy of those particles, i.e. decelerate them to the lowest possible…

A special Xenon run for NA61/SHINE

Earlier in October, the Large Hadron Collider had a special test run of colliding xenon nuclei; a new flavour compared to the standard proton and lead collisions foreseen in the LHC experimental programme. Xenon collisions were requested by NA61, a…

Another milestone for the BASE collaboration

In a recent publication in the Nature magazine, the BASE collaboration reports on the first high-precision measurement of the antiproton magnetic moment with parts per billion uncertainty (see https://www.nature.com/articles/nature24048). The…

ALPHA experiment takes a closer look at antimatter

The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. The results were published in www.nature.com/nature/…

How heavy is the proton?

To determine the mass of a single proton more accurately, the group of physicists from the Max Planck Institute for Nuclear Physics in Heidelberg and RIKEN in Japan performed an important high-precision measurement in a greatly advanced Penning…

Exploring the dark sector with NA64

The field of dark matter (DM) particle physics is at an interesting stage, as key discoveries are anticipated. However, despite the intensive direct, indirect and LHC searches, the experiments have not yet yielded unambiguous Dark Matter (DM)…
