All matter that exists in the Universe is made up of particles. Each type of particle fulfills a different function.
The interaction between different types of particles makes the Universe possible as we know it.
There are two kinds of particles: fermions and bosons. Fermions form the mass of matter. Bosons are responsible for applying to that mass the four fundamental forces: electromagnetism, strong nuclear force, weak nuclear force and force of gravity.
Elementary particles are the smallest parts or portions into which matter can be divided.
The fermions Elementals are quarks and leptons:
- Quarks: they join together in groups of three to form larger particles, such as protons and neutrons.
- Leptons: They are very light particles, such as electrons, muons and neutrinos.
The bosons Elementals are photons, gluons and others:
- Photons: responsible for electromagnetism.
- Gluons: They deal with the strong nuclear force.
- Bosons W and Z: weak nuclear force managers.
- Graviton: in charge of gravity, although it has not yet been seen.
- Higgs' Boson: responsible for the particles having mass. It explains all the matter we see, and that is why it is called "the divine particle."
What are hadrons?
When several elementary particles come together, they form composite particles that we call hadrons.
Composite fermions are barions. The best known are protons and neutrons. Compound bosons are inns. The best known is the pion. The CERN hadron collider is a very important particle physics experiment.
Scientists from all over the world participate in it. Accelerates particles (hadrons) to almost the speed of light and makes them collide with each other to see how they behave. Through these experiments, CERN seeks information on types of undiscovered particles, the composition of the Universe, its origin, and how the forces act with each other.
