» For the particle collider, see Large Hadron Collider.In particle physics, a hadron (from the, hadrós, "stout, thick")'s a bound state of quarks. Hadrons are held together by the strong force, similarly to how molecules are held together by the electromagnetic force. There're two subsets of hadrons: baryons and mesons; the most well known baryons are protons and neutrons. Introduction According to the quark model, the properties of hadrons are primarily determined by their so-called valen… (More on Hadrons)
