The research board of CERN, the European Organization for Nuclear Research, on March 5 approved a new experiment at the Large Hadron Collider in Geneva, the world’s largest particle accelerator, to search for evidence of fundamental dark matter particles. The Forward Search Experiment — or FASER — seeks to answer one of the outstanding questions in particle physics: What is dark matter made of?

“There is strong evidence that most of the matter in the universe — about 85 percent — is dark matter, and that dark matter is made up of an unknown class of fundamental particles,” said Shih-Chieh Hsu, an associate professor of physics at the University of Washington and member of the FASER team. “The identity of dark matter particles is a major mystery in particle physics, and one that we think FASER could help solve by identifying a class of particles associated with dark matter.”
