Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped ...

According to our current understanding of the universe, equal amounts of matter and antimatter should have been produced in the Big Bang, then both annihilated. However, the universe is dominated by ...

A team of theoretical physicists has proposed a new particle existing in a warped fifth dimension that could bridge ordinary matter with dark matter. The model, published in The European Physical ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest ...

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 ...

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, ...
