CLOUD experiment makes its own clouds to study

The Intergovernmental Panel on Climate Change (IPCC) recognizes aerosols (small nanometer to micrometer sized particles suspended in air) as the single biggest source of uncertainty in human-driven climate change. Atmospheric aerosol particles are…

Exotic radioactive molecules could reveal physics beyond the Standard Model

The first spectroscopic study of radium monofluoride (RaF) suggests that these radioactive molecules can be used to perform high precision tests of the Standard Model of particle physics. The study was done at ISOLDE, CERN’s radioactive beam…

ALPHA publishes first measurements of quantum effects in antimatter

The ALPHA collaboration at CERN has reported the first measurements of fine structure effects and Lamb shift in the energy structure of antihydrogen that provide another test of comparison between antimatter and ordinary matter. The results,…

ISOLDE dives deeper in the mystery of the odd-even staggering effect

In a recent paper, to appear in Nature Physics in the next weeks (arXiv:1911.08765v3), the CRIS collaboration, located at the ISOLDE facility in CERN, presents measurements of charge radii of exotic copper isotopes that shed further light on one of…

POLAR-2 project enters final design stage

The POLAR-2 project is a follow-up of the POLAR mission that was launched in 2016, mounted on the exterior of the Chinese Spacelab Tiangong-2. Following its application to the Recognized Experiment Committee earlier this year, it has been…

MUonE experiment gears up to chase whiff of new physics

A new proposed project, MUonE, was described on the EP Newsletter few months ago [2].  It is an experiment aiming at helping in understanding the long-standing discrepancy between the experimental value and the Standard Model (SM)…

Civil engineering for FASER

Civil engineering work to enable the installation of the FASER experiment in TI12, which is the former LEP injection tunnel from the SPS, successfully completed this month. The FASER experiment is designed to detect new physics particles…

FASERν: looking for high-energy collider neutrinos

In December 2019 a proposed upgrade of the FASER detector designed to study neutrinos at the LHC was approved by CERN. The new detector called FASERν will be placed in front of the main FASER detector, 480-m in front of the ATLAS collision…

PUMA: Exploring exotic nuclear phenomena with antimatter

PUMA is a new experiment proposed at both the CERN AD and ISOLDE facilities, that would for the first time transport antiprotons trapped at AD/ELENA to ISOLDE, by carrying them in a trap loaded onto a truck. The antiprotons would then be used…

CAST: from Solar to Dark Matter Axions searches

*/ CERN’s Axion Solar telescope (CAST) has been running since 2003 searching for the axion: a hypothetical particle introduced in 1978 as a consequence of the Peccei-Quinn mechanism aiming to solve the strong CP problem, i.e why is the neutron…
