Let’s take a look at why we need quarks to understand the world ... Aren’t elementary particles like protons and neutrons enough? Why do we need to break them up further, to understand ...

It’s not much to look ... quarks get lots of attention. But they’re about 1% of what’s inside a proton. Protons also contain another kind of fundamental particle that acts like glue between ...

including particles with higher rest masses (like the heavier quarks) and, eventually, a fraction of gluons that completely dominates. The more energetically you look, the denser the sea of ...

Quarks are the particles in the standard model of particle physics that bind together and comprise particles like protons and neutrons.
