What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped ...

Kaons have several known common ways of decaying, but the one in this paper is so rare that scientists weren’t sure it existed before now. Their model predicted they’d see less than a quarter of one ...

According to the standard model, this shouldn’t happen—hinting that new particles or even forces of nature may influence the process.

New research shows the W boson —a tiny particle fundamental to the formation of our universe—is heavier than scientists expected. This discovery goes against the Standard Model of particle ...

Recently, a series of precise measurements of already known, bog-standard particles and processes have threatened to shake up physics.

An ultraprecise measurement of the mass of a subatomic particle called the W boson may diverge from the Standard Model, a long-reigning framework that governs the strange world of quantum physics.

New measurement of wobbling muons back up previous findings – potentially challenging the Standard Model of Particle Physics.

Purdue physicists part of discovery of rare particle decay predicted by the Standard Model August 19, 2013 Red lines show the disintegration of a B-sub-s into two muons in the CMS camera at the Large ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations ...
