The many faces of ISOLDE

You will stand across the street from the ISOLDE facility, when visiting CERN’s medical center, fire fighters, raw materials store, transport teams, or goods reception service. Located centrally at the Meyrin site (https://videos.cern.ch/record/…

Cooling a particle from a trap away

The BASE experiment, located at CERN’s Antiproton Deccelerator (AD) performs some of the most precise measurements with antimatter in the world – namely measuring the magnetic moment and charge-to-mass ratio of a single trapped antiproton. With…

FASER Detector Installation

During March the FASER detector was successfully installed into the LHC complex. FASER, a new small LHC experiment, designed to search for light, weakly interacting new particles in the LHC collisions was proposed in 2017, and after review by the…

Pinning down the muon (g-2) anomaly at the CERN SPS

The Dirac equation predicts the muon gyromagnetic ratio g=2. Loop effects from quantum field theory lead to a small deviation from this value, parameterized by the so called anomalous magnetic moment which is defined as aμ=(g-2)/2. The difference…

ISOLDE determines precise nuclear moments by devising novel experimental technique

Nuclear quadrupole moments (Q), a measure of charge asymmetry in nuclei, are experimentally accessible via the quadrupole interaction frequency νQ=eQVzz/h. To extract Q from this information one needs to know Vzz, the electric-field gradient at the…

Designing the SND@LHC experiment

SND@LHC is a newly proposed, compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity range of 7.2 < 𝜂 < 8.6, complementary to all the other experiments at the LHC,…

BASE develops a new technique to detect ultralight dark matter.

In a recent work published in Physical Review Letters [1], the Baryon Antibaryon Symmetry Experiment (BASE) at CERN has placed new limits on a possible coupling between photons and hypothetical axionlike dark matter particles with masses between 2.…

Latest Results from the AMS on the International Space Station

 The Alpha Magnetic Spectrometer, AMS, is a particle physics detector operating on the International Space Station (Figure 1) since May 2011 with the aim to address long-standing open questions in fundamental physics, such as the matter-antimatter…

Do opposites attract? ALPHA-g prepares to explore antimatter gravity

Stuff falls down. This is the universal experience we all have with the gravitational interaction of matter on Earth. Yet one may still wonder if this holds true in the case of the most elusive stuff you can imagine dropping: antimatter. Might it be…

From COMPASS to AMBER: exploring fundamental properties of hadrons

The quest to fully understand the internal structure of hadrons, in particular the dynamics as well as the spatial and momentum distributions of their constituents - the partons -, inspired a large community of theoreticians and experimentalists to…
