Newly released observations of the top quark -- the heaviest of all known fundamental particles -- could topple the standard model of particle physics. Data from collisions at the Tevatron particle ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

The 'Standard Model,' which details the fundamental principles that constitute and govern the universe with 17 elementary particles and forces, is called the most precise theory ever created by ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. There were a huge variety of potential new physics signatures that ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

One of the best chances for proving beyond-the-standard-model physics relies on something called the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The standard model insists that the CKM matrix, which ...

The inside of the LHC, where protons pass each other at 299,792,455 m/s, just 3 m/s shy of the speed of light. Particle accelerators like the LHC consist of sections of accelerating cavities, where ...

The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, while omitting gravity) in the universe, ...
