In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypoethical particle, known ...

Some cosmic rays come from the sun, some from elsewhere in our Milky Way, and others, called extragalactic cosmic rays, trace ...

For more than a decade, physicists have argued (and counter-argued) that a subatomic particle can be separated from certain quantum properties, such as its spin—a phenomenon known as the Cheshire cat ...

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration were sifting through data from the Large Hadron Collider (LHC) and ...
