Researchers at the large experiments (CMS, ATLAS, ALICE and LHCb) at the world's largest particle accelerator (LHC) at CERN are investigating the building blocks of the universe and the fundamental forces, but are also searching for the unknown.

In March 2021, evidence of something new was found at the LHCb experiment: Some particles do not behave quite as expected.

Find out why researchers expect to find new particles or forces, how they search for them with the large detectors at CERN and how these detectors work. Using a 1:10 scale model of one of the LHC detectors (CMS detector), you can interactively find out how researchers from UZH and around the world detect various elementary particles.
