The theory of **Gluons** ($\pu{g}$) are exchanged for matter to feel **strong nuclear** force: the strongest interaction between particles. These particles are heavy (120 MeV/c2) and short-lived, thus giving the force a very short range. -**Photons** ($\pu{\gamma}$) are exchanged for matter to feel **electromagnetic** force: the second strongest force responsible for magnetism and electric force.

These particles have a rest mass of zero and travel for an infinite distance until they are absorbed. The **W+, W-, and Z0** bosons are together responsible for the weak nuclear force and are the third strongest force. These particles have a heavy rest mass (80 GeV/c2 for Ws, 91 GeV/c2 for Z) and so are even more limited in range than gluons.
