What are fermions?Show answer
All ordinary matter is built from two families of fermions:
What are bosons?Show answer
In the Standard Model, forces act through the exchange of particles called gauge bosons:
What are the four fundamental forces?Show answer
There are four fundamental interactions in nature:
What are hadrons?Show answer
Particles built from quarks are called hadrons. A baryon, such as the proton or neutron, is made of three quarks. A meson is made of a quark and an antiquark, such as the pion exchanged between nucleons. The strong force, carried by gluons, binds the quarks so tightly that they can never be isolated, a property called confinement: trying to pull a quark out instead creates new quark-antiquark pairs.
