About Hadrons

Hadrons, though extremely small, are not fundamental particles as they are made of quarks.

Hadrons include:

• Baryons - A type of hadron made of 3 quarks.
  • Proton - A type of baryon with a mass of 1.67x10^-27kg and a charge of 1.60x10^-19 Coulombs, made of 2 Up-quarks and 1 Down-quark.
  • Neutron - A type of baryon with a mass of 1.67x10^-27kg and zero charge, made of 2 Down-quarks and 1 Up-quark.
• Mesons - Types of hadron consisting of a quark-antiquark pair.

Hadrons are affected by the:

• Strong Nuclear Interaction
• Weak Nuclear Interaction
• Electromagnetic Interaction
• Gravitational Interaction
