The quarks inside atoms move slower than the quarks inside free-floating protons and neutrons. But why?

The world's largest atom smasher has "given birth" to a set of four ultraheavy particles — called top quarks.

The LHC's ALICE experiment detected a 'dead cone' in the aftermath of a proton-proton collision, paving the way for the direct measurement of the mass of a quark.

Protons can contain a charm quark, an elementary particle 1.5 times heavier than the proton itself.

The top quark is about 100 trillion times heavier than the up quark. But why?

A team of physicists has found that the remnant of a neutron star merger observed in 2019 has just the right mass to be a strange hypothetical quark star.

Three scientists who laid the groundwork for the understanding of the odd "entangling" behavior of quantum particles have received the 2022 Nobel Prize in Physics.

A new understanding inspired by string theory shows that our universe may be more stable than we previously thought.
