Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

In particle physics, a hadron is a composite subatomic particle made of two or more quarks that are held together by the strong nuclear force. Pronounced, the name is derived from Ancient Greek ἁδρός (hadrós) 'stout, thick'. They are analogous to molecules, which are held together by the electromagnetic force. Most of the mass of ordinary matter comes from two hadrons: the proton and the neutron, while most of the mass of the protons and neutrons is in turn due to the binding energy of their constituent quarks, due to the strong force.
