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 ...

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 ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

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 ...

His work paved the way for the discovery of the Higgs boson, which explained how particles acquire mass, solving one of the ...
