Physicists have spent decades treating mass as something particles simply possess, a built-in feature explained by the Higgs field but not fully illuminated by it. A new wave of research is now ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

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 ...

After years of searching, scientists at the Micro Booster Neutrino Experiment (MicroBooNE) have ruled out the possibility of the existence of a sterile neutrino, a hypothetical particle that had long ...

Scientists at CERN, the home of the Large Hadron Collider, have just observed an astoundingly rare phenomenon at the subatomic level that could lead to a new understanding of the standard model of ...
