Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests the missing ...

The discovery of the Higgs boson hasn’t led to an explosion of new physics as many predicted. Now, some scientists think that hidden physics may be hiding beyond LHC’s view.

A philosopher has put forward an argument for rethinking how particles are defined within the standard model of particle ...

Dark matter, the mysterious substance that holds galaxies together, may be connected to a hidden fifth dimension of space, ...

Add Yahoo as a preferred source to see more of our stories on Google. An engineer works on equipment for the LHCb experiment inside the tunnel of the Large Hadron Collider. Physicists know that their ...

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut ...

A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.

any generation of Standard Model fermions transforms as the direct sum of six irreducible representations: These correspond to the six types of left-handed fermion: q L, d R, u R, ℓ L, e R, ν R. Six ...

The Higgs boson was supposed to be the final piece of the Standard Model puzzle. Confirmed at the Large Hadron Collider in 2012, it completed a theoretical framework decades in the making. But a ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than others. Reading time 5 minutes For all practical purposes, the Standard ...
