The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on ...

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

Physicists have achieved a long-sought goal in demonstrating quantum entanglement using the momentum of atoms, rather than ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

CERN’s LHCb experiment reported the observation of the doubly charmed baryon Ξcc⁺, a result that confirms upgraded detector ...

They say you can never trust an atom because they make up everything. This week, we’re shrinking down and getting literally into the heart of the matter. We’ve covered the periodic table and all its ...

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

Leon Lederman, whose ingenious experiments with particle accelerators deepened science’s understanding of the subatomic world, died early Wednesday in Rexburg, Idaho. He was 96. Leon Lederman, whose ...
