Elementary Parcile

Matter at fundamental level, it’s not made up of particle. But instead, it made up of field.

But to understand the standar model, it’s more convenience to use the language of particle.

Fermions are matter particles.

Bosons are force particles.

Distinction between fermions and bosons

Lies in the quantum world. Particles that obey Pauli Exclusion Principle, they’re Fermions. Otherwise, they’re bosons.

Everything can be reduced to just three matter particle (Fermions)

  • Electron
  • Up quark
  • Down quark
  • Electron neutrino

Proton have: two up quarks and a down

Neutron have: two down quarks and an up
