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

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

The muon mismatch was caused by calculation limits, not a new force. Improved methods bring theory and experiment into close ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?”. Resisting the temptation to sarcastically ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most ...

From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

A team of theoretical physicists has proposed a new particle that could act as a bridge between ordinary matter and dark matter, existing in a warped fifth dimension beyond space and time. Their model ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...
