An experiment that probed particles called gluons, which contain most of the mass of a proton, has revealed that a proton’s radius alters depending on whether you look at the particle's charge or mass

Physicists are still puzzled by a new measurement of a fundamental particle called the W boson, which doesn't agree with our existing understanding of the universe

The particles inside a proton move around when exposed to electric and magnetic fields, causing it to deform, but this behaviour isn't well understood

By trapping a single electron in an isolated chamber cooled to near absolute zero, physicists were able to measure the particle's magnetic moment - a key quantum property - at a precision of 1.3 parts in 10 trillion

The textbook description of a proton says it contains three smaller particles - two up quarks and a down quark - but a new analysis has found strong evidence that it also holds a charm quark

A proposed particle detector contains strands of hanging DNA that are severed when high-energy particles pass through – and it could allow us to track particle paths with nanoscale precision

The standard model of particle physics has stood the test of time for decades, but now a new measurement of a particle called the W boson could indicate a chink in its armour
