Particle physics in Belgium takes place at the universities of Antwerp, Brussels (both Dutch- and French-language universities), Gent, Leuven, Louvain-la-Neuve and Mons, with activities in many experiments. The largest groups are in the CMS-experiment at the LHC and in IceCube, but there is also participation in NA62, JUNO and SoLid. The outreach activities are many and diverse, ranging from Masterclasses to regular lectures for general public. Recently a major effort began to establish Gravitational Waves as a research line in almost every university, with participation in Virgo and the Einstein Telescope Pathfinder projects.
