Our most powerful particle accelerators mimic near-light speeds of cosmic particles. But no upgrade may be capable of ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — ...

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision ...

Scientists have proposed a new kind of subatomic particle to explain another particle’s mysterious disintegration. The kaon, a special case of meson particle, is made of one quark and one antiquark.

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming ...
