CLOUD experiment makes its own clouds to study

by Hanna Manninen, CLOUD Run Coordinator

CLOUD collaboration ramps up activities preparing for a new physics run. 


Exotic radioactive molecules could reveal physics beyond the Standard Model

by Gerda Neyens, ISOLDE Collaboration Spokesperson

ISOLDE, CERN’s radioactive beam facility enables the first spectroscopic study of radium monofluoride (RaF); a radioactive molecule tht can be used to probe new physics beyond the Standard Model. 


The new results usher a new era of high-precision tests between matter and antimatter.

First measurements of charge radii of the Cu isotopes using ISOLDE's Collinear Resonance Ionisation Spectroscopy (CRIS) method shed more light on one of the most pertinent open problems in nuclear theory.


POLAR-2 project enters final design stage

by Merlin Kole (University of Geneva)

China appears to be preparing to deorbit its Tiangong-2 space lab ...The POLAR-2 collaboration builds a compact satellite-born detector promising a new era in Gamma-Ray Bursts studies. 

MUonE experiment gears up to chase whiff of new physics

by Clara Matteuzzi & Luca Trentadue (INFN)

The proposed MUonE experiment plans to shed light on the muon anomalous magnetic moment; one of the most intriguing questions in particle physics.

Civil engineering for FASER

by Jonathan Gall & Eliseo Perez-Duenas (CERN)

Civil engineering work to enable the FASER experiment to be installed in TI12 during LS2 has successfully completed.

PUMA: Exploring exotic nuclear phenomena with antimatter

by Alexandre Obertelli (TU Darmstadt, PUMA spokesperson) François Butin (CERN, PUMA project manager)

The proposed experiment would for the first time transport antiprotons trapped at AD/ELENA to ISOLDE where they will be used for nuclear physics experiments.


CAST: from Solar to Dark Matter Axions searches

by Marios Maroudas (University of Patras), Yannis Semertzidis (Center for Axion and Precision Physics Research, IBS)

CAST prepares to leap further into the dark sector following successful installation of new resonant microwave cavities.

Following six successful years of operation, the AMS-02 experiment at the ISS recently successfuly performed a major upgrade, thus extending its lifetime and giving us more data to test theories for new physics.
