The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at ...

Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

Breaking the rules is exciting, especially if they have held for a long time. This is true not just in life but also in particle physics. Here the rule I'm thinking of is called “lepton flavor ...

Researchers at CERN's Large Hadron Collider have observed a rare B meson decay pattern that deviates from Standard Model predictions by four standard deviations. The result, from the LHCb experiment, ...

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light speed, creating a "quark-gluon plasma" that lasted for ...

Top result: An artist's impression of top-quark entanglement. The line between the particles emphasizes the non-separability of the top-quark pair, which is produced by LHC collisions and recorded by ...

Physicists observed the first clear evidence that quarks create a wake as they speed through quark-gluon plasma, confirming the plasma behaves like a liquid. (Nanowerk News) In its first moments, the ...
