'Tantalizing' results of 2 experiments defy physics rulebook

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both baffled and thrilled.

New exotic matter particle, a tetraquark, discovered

Today, the LHCb experiment at CERN is presenting a new discovery at the European Physical Society Conference on High Energy Physics (EPS-HEP). The new particle discovered by LHCb, labeled as Tcc+, is a tetraquark—an exotic ...

Voyager 1 may have left the solar system

While there's no official word from NASA on this, the buzz around the blogosphere is that Voyager 1 has left the Solar System. The evidence comes from this graph, above, which shows the number of particles, mainly protons, ...

What comes after the Higgs boson

Ten years ago this week, two international collaborations of groups of scientists, including a large contingent from Caltech, confirmed that they had found conclusive evidence for the Higgs boson, an elusive elementary particle, ...

CERN lab on the hunt for dark matter

Europe's physics lab CERN on Tuesday said it was planning a new experiment to look for particles associated with dark matter which is believed to make up some 27 percent of the universe.

The quantum field theory on which the everyday world supervenes

The laws of physics underlying everyday life are, at one level of description, completely known, and can be summarized in a single elegant—if quite complex—equation. That's the claim physicist Sean Carroll, an SFI Fractal ...
