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...

There's a specter haunting the tunnels of a particle accelerator at CERN.

A strange phase of matter that previously existed purely in the realm of theory has finally been detected in a real material.

Maximizing the energy output of nuclear fusion is a crucial milestone in establishing it as the primary energy source for the future. Thus far, the accomplishment has been limited to a single system – the inertial fusion method used by the National Ignition Facility (NIF). Recent research on a comparable methodology indicates that the NIF …

JILA, established by NIST and the University of Colorado Boulder, has played a pivotal role in advancing precision timekeeping through optical atomic clocks. These devices achieve extraordinary time measurement accuracy by utilizing the fundamental properties of atoms. Despite their advancements, th
