The Daya Bay Neutrino Experiment has produced the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their flavor.
A team of young scientists paused their new physics searches to develop an innovative machine-learning tool, which is now helping them narrow in on a rare and messy decay of the Higgs boson.
Project Poltergeist led to the discovery of the ghostly particle. Sixty years later, scientists are confronted with more neutrino mysteries than ever before.
