How many kinds of elementary particles should I say there are? In experiments at the Large Hadron Collider, physicists smash ...

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 hunt is on for leptoquarks, particles beyond the limits of the standard model of particle physics —the best description we have so far of the physics that governs the forces of the Universe and ...

Despite its tremendous success in predicting the existence of new particles and forces, the standard model of particle physics, designed over 50 years ago to explain the smallest building blocks of ...

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 ...

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. (Francis ...

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 ...

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 ...

Wondering whether whether Dark Matter particles actually are produced inside a jet of standard model particles, led researchers to explore a new detector signature known as semi-visible jets, which ...

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 ...

If you ask a physicist like me to explain how the world works, my lazy answer might be: “It follows the Standard Model.” The Standard Model explains the fundamental physics of how the universe works.

Breaking the rules is exciting, especially if they have held for a long time. This is true not just in life but also in particle physics. Here the rule I'm thinking of is called “lepton flavor ...
