Last Thursday, a global audience of CERN alumni had their curiosity well and truly sparked thanks to Dr Dave Barney's fascinating talk on the CMS High-Granularity Calorimeter, followed by a lively Q&A session, expertly moderated by Dr Rebeca Gonzalez Suarez.

The ALPHA collaboration at CERN has succeeded in cooling down antihydrogen atoms – the simplest form of atomic antimatter – using laser light.  Comparing such measurements with those of the well-studied hydrogen atom could reveal differences between matter and antimatter atoms. Such differences, if present, could shed light on why the universe is made up of matter only, an imbalance known as matter–antimatter asymmetry:

Staying with antimatter, on 17 March 2021, the CERN Research Board approved the development of two new experiments to carry antiprotons from the Antimatter Factory to other facilities, for antimatter and nuclear-physics studies. The new experiments, called BASE-STEP and PUMA, are expected to be operational in 2023: https://home.cern/news/news/physics/cern-approves-two-new-experiments-transport-antimatter

Finally, CERN’s Knowledge Transfer group will be offering a training course on “Finding Happiness in Patent Information Databases”, tackling the anatomy of patents, patent information databases and their importance. CERN Alumni are welcome to enrol! https://home.cern/news/announcement/knowledge-sharing/training-session-finding-happiness-patent-information-databases
