CLOUD experiment reveals a major new source of marine aerosol particles
CLOUD experiment reveals a major new source of marine aerosol particles Clouds form when water vapour condenses onto tiny airborne particles known as aerosols. Once these particles grow larger than about 50 nanometres, they can act as cloud condensation nuclei, or CCN, on which cloud droplets form. Increased aerosol particles influence the climate in several

The ISOLDE Improvement Programme
The ISOLDE Improvement Programme The ISOLDE Improvement Programme (IIP) brings together a series of upgrades and consolidation activities to maintain and further develop the ISOLDE facility. The programme includes projects addressing the accelerator infrastructure, beam production, and delivery systems, and experimental facilities, with the objective of improving operational flexibility, reliability, and long-term sustainability. Among the

FASER opens new windows on dark sectors and TeV neutrino physics
FASER opens new windows on dark sectors and TeV neutrino physics The FASER experiment has presented a series of new results that highlight the growing breadth of its physics programme at the LHC. These include a search for dark photons with the main FASER detector, a first search for neutrino-induced charm production with FASERν, and

PUMA – Antiprotons as a precision probe for the tail of nuclear density
PUMA – Antiprotons as a precision probe for the tail of nuclear density Understanding the nuclear structure of atomic nuclei away from the valley of stability remains one of the central challenges of nuclear physics and astrophysics. In particular, the dilute outer regions of neutron-rich nuclei can exhibit phenomena such as neutron halos and neutron

Moving antimatter beyond the lab
Moving antimatter beyond the lab For decades, antimatter experiments have been bound to a single place: the laboratory in which the particles are produced and trapped. At CERN’s Antimatter Factory, antiprotons are routinely produced, decelerated and confined in Penning traps, where electric and magnetic fields are used to store charged particles for high-precision studies. Yet

Probing lithium dynamics at buried interfaces with β-detected NMR at ISOLDE
Probing lithium dynamics at buried interfaces with β-detected NMR at ISOLDE Spin-polarised probes have been central to nuclear and particle physics since the discovery of parity violation by Chien-Shiung Wu in 1956, who detected asymmetric emission of β-radiation from low-temperature 60Co in a magnetic field. The directional distribution of radiation from aligned spins provides access

NA62 sharpens the picture of one of nature’s rarest particle decays
NA62 sharpens the picture of one of nature’s rarest particle decays The NA62 experiment at CERN has achieved a major milestone in flavour physics with the first observation of one of the rarest particle decays ever measured. The process — the decay of a positively charged kaon into a pion and a neutrino–antineutrino pair —

MUonE: A new path to hadronic vacuum polarization and the running of α
MUonE: A new path to hadronic vacuum polarization and the running of α The MUonE Collaboration [1] is making excellent progress towards developing a final proposal for an experiment that will measure the running of the electromagnetic coupling (alpha) by mapping out the differential cross section for muon–electron elastic scattering. The effective coupling strength increases

Sympathetic Cooling Opens a New Era for Antihydrogen at CERN
Sympathetic Cooling Opens a New Era for Antihydrogen at CERN A major milestone has been reached at CERN’s Antimatter Factory. Using an innovative technique to cool positrons with laser-cooled beryllium ions, the ALPHA collaboration has increased the rate of antihydrogen production by a factor of eight. The advance, reported in Nature Communications, has transformed the
