kvark

kvark

One of the fundamental constituents of matter. These particles posses spin ?. They come in six flavors: up (u), down (d), strange (s), charm (c), bottom (b), and top (t). Only the up and down quarks are commonly found outside of accelerators. Protons and neutrons are composed of up and down quarks.
