Classical physics taught that light waves pass through each other unaffected, but quantum mechanics couldn’t resist the ...

Physicists have discovered that when beams of light interact at the quantum level, they can generate ghost-like particles ...

But even as the Standard Model was emerging in the 1960s, theorists recognized that something else was needed to explain many of its features, including why some particles have mass while others ...

The magnetic moment of the muon—a tiny property of a tiny particle—has long puzzled physicists. Experiments and theory haven’t quite matched up, leaving open the thrilling possibility of discovering ...

Physicists would dearly love to find new particles, but there's no sign of them in colliders like the LHC. Now we have found ...

“The level of control the authors have achieved over an individual antimatter particle is unprecedented,” says Dmitry Budker, ...

A spectacular signature of Physics Beyond the Standard Model would be the observation of a particle with different quantum numbers than the ones allowed for Standard Model particles: for instance a ...

Neutrinos, ghostly particles barely interacting with matter, may secretly be reshaping the fates of massive stars. New ...

For Standard Model particles, we can calculate these corrections and feedback interactions, which is how theorists predicted the mass of the Higgs boson well before it was detected.
