Testing CPT-symmetry and the Weak Equivalence Principle with Proton/Antiproton Clock Comparisons

Even though the Standard Model of Particle Physics is incredibly successful and provides extremely accurate predictions for many physical quantities and mechanisms, the model is known to be incomplete. For instance, it fails in explaining the…

MoEDAL’s Searches for Magnetic Monopoles Produced via The Schwinger Mechanism

Magnetic monopoles (MMs) are hypothetical fundamental particles that carry isolated magnetic charge that are arguably the most important particle yet to be discovered. In 1931 Dirac first showed that a  MM was compatible with quantum mechanics [1]…

ISOLDE's Solenoidal Spectrometer (ISS): a new tool for studying exotic nuclei

The majority of atomic nuclei exist away from the valley of beta-stability, so it is perhaps unsurprising that in studying them nuclear physicists have discovered emerging phenomena not seen in stable nuclei. Changing shell structure, evolving…

New prospects for the Physics Beyond Colliders programme

Particle physics is often equated with high energy collider experiments. However, over recent years it has become increasingly clear that high intensity and high precision experiments offer significant, complementary opportunities to explore physics…

Prestigious Award for Quantum Logic Spectroscopy

In October, the prestigious Dissertation Prize of the Section Atoms, Molecules, Quantum Optics and Plasmas (SAMOP) of the German Physical Society was awarded to Peter Micke for his seminal work demonstrating quantum logic spectroscopy on highly…

Transforming NA62

The main goal of the NA62 experiment, located in CERNs North Area, is to precisely measure the K+→π+νν̅  branching fraction, which is highly sensitive to new physics processes. The analysis of data collected during 2016-2018 led to the most precise…

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…
