The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

Neutrinos are notoriously aloof, but it’s not entirely their fault. Neutrinos are some of the most abundant particles in the universe, and they are everywhere. Every second, more than 6 trillion ...

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning—but many researchers are not giving up on it yet.

Yesterday, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide.

Scientists don’t yet know what dark matter is made of, but they are full of ideas. Although nearly a century has passed since an astronomer first used the term “dark matter” in the 1930s, the elusive ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

Physicists and archaeologists are teaming up to provide research opportunities for Black and Hispanic undergraduates.

Scientists around the world are testing ways to further boost the power of particle accelerators while drastically shrinking their size.

Quantum entanglement, doubted by Einstein, has passed increasingly stringent tests. Over 12 billion years ago, speeding particles of light left an extremely luminous celestial object called a quasar ...
