Experiments on a quantum material have revealed for the first time what might be a particle similar to the hypothetical graviton particle.
In a talk at the ongoing Rencontres de Moriond conference, the ATLAS collaboration presented the result of its latest test of a key principle of the Standard Model of particle physics known as lepton flavour universality. The precision of the result is the best yet achieved by a single experiment in decays of the W boson and surpasses that of the current experimental average. Most elementary particles can be classed into groups or families with similar properties. For example, the lepton family includes the electron, which forms the negatively charged cloud of particles surrounding the nucleus...
Scientists are aiming to find hidden sector or "ghost" particles in a new £100million experiment to be undertaken at Cern that could provide some answers about the origins of the universe
The project marks "a new era" in the search for mystery particles, according to its leader.
New theoretical research suggests that a mysterious form of matter called "unparticles" could be the driving force behind the expansion of the universe.
