European scientists have discovered a new subatomic particle containing a never-before-seen combination of quarks, the most basic building blocks of matter. The particle, a baryon dubbed Xi cc, contains two heavy "charm" quarks and one "up" quark, and has about four times the mass of ...
Scientists at Europe's physics research center, CERN, are preparing to unwrap the biggest trove of data yet from the Large Hadron Collider (LHC), three years after they confirmed the existence of the elusive Higgs boson. "In the life of accelerator physics there are few moments ...
Finding one of the building blocks of the universe is a tough act to follow. That's the task confronting Fabiola Gianotti when she takes over as head of CERN, the Geneva-based atom-smasher that discovered the Higgs boson particle and landed the Nobel Prize in physics ...
The first results from a $2 billion instrument aboard the International Space Station offer tentative support for the theory that exotic dark matter, invisible but abundant, permeates the universe.
