BRAINCAKEHadrons
There are two types of hadrons - baryons and mesons. Baryons are made of three quarks (qqq) and include protons and neutrons.
Mesons are made of quark -antiquark pairs and include π mesons and K mesons.

Key terms in this lesson
- Strong nuclear force
- The short-range attractive force between nucleons that overcomes the electrostatic repulsion between protons and holds the nucleus together, becoming repulsive at very short separations.
- Weak nuclear force
- The fundamental interaction responsible for beta decay, in which particles interact through the exchange of W bosons.
- Quark
- A fundamental particle that combines with other quarks to make up hadrons; at A-level, up, down and strange quarks are considered.
