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

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

In some types of helium and hydrogen, protons are more than six times as likely to pair up than they are in other atoms – which may mean there is something we don’t understand about the strong nuclear force

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

Twenty years ago, researchers saw hints of the existence of a type of exotic matter made of four neutrons. Now, researchers have found the clearest evidence it exists yet

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
2 February 2022
Researchers have used the strongest magnetic field ever measured to search for exotic particles called magnetic monopoles, but they came up empty

After decades of looking, physicists are no closer to discovering theorised particles that could help solve ongoing problems in physics
