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 ...

The quarks, antiquarks, and gluons of the standard model have a color charge, in addition to all the other properties like mass and electric charge that other particles and antiparticles possess. All ...

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 ...

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 ...

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 ...

THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...

Harry Cliff is a member of the LHCb Collaboration, though he was not directly involved in the work described in this article. Everything you see around you is made up of elementary particles called ...
