ISOLDE lays the ground for CP violation tests with radioactive molecules

All atoms heavier than bismuth, which has 83 protons, are radioactive and their isotopes have short half-lives, with few exceptions. As a result, the study of heavy atoms and their molecular compounds is complicated by the radioactive decay of the…

First Physics Results from the FASER Experiment

FASER is a new small LHC experiment designed to search for light, weakly interacting, long-lived beyond-standard model particles such as dark photons and to detect high energy neutrinos produced in proton-proton collisions. The FASER detector is…

ANUBIS: a guide into the dark sector

The ancient Egyptians believed Anubis was a jackal-headed god who accompanied kings to the underworld. Today we know better: ANUBIS is a proposed extension to the ATLAS detector to explore the dark sector by searching for long-lived particles (LLPs…

Lighting the dark with NA64: news from Light Dark Matter searches

The existence of Dark Matter (DM) has been inferred by Cosmology and Astrophysics through its gravitational effects. However, its microscopic nature remains one of the most pressing questions in particle physics. Scenarios in which the DM is a…

Radioactive ion beams at ISOLDE bring the nuclear clock a tick closer

The precise measurement of time and frequencies has always played an important role in the history of science. Since the adoption of the caesium-133 standard as the definition of the second within the Système International (SI) in 1967, a network of…

HIKE collaboration targets a new era of kaon experiments

The recently proposed High Intensity Kaon Experiments (HIKE) project offers a long-term vision for a research programme at CERN, covering experimental searches in the kaon sector that could enable a new generation of searches and indirectly probe…

MILLIQAN gets ready to have a look at the dark

The milliQan collaboration is on track to finish the installation and commissioning of their Run 3 detector before the end of the YETS, Components of both the “bar” and “slab” detectors have been placed in a tunnel above the CMS experimental cavern…

The birth of NanoCal

High-performance electromagnetic calorimeters often make use of inorganic crystal scintillators. Their high density makes them well suited for the construction of large homogeneous detectors where the scintillating material simultaneously serves as…
