### substance | particle | boson:

Gluon
* also have color charge.
  - massless quanta of the strong-interaction field
  - massless, like the photon
  - particles which bind quarks together to form protons, neutrons, and other stuff
* are the carrier of the strong force, and hold the quarks together
  - particles of strong interactions
* are the force carrier, just like photons are the carrier of the electromagnetic force
  - particles which hold quarks, another subatomic particle, together
  - mediators for the forces that bind quarks into larger packages
  - particles which carry the strong nuclear force
* carry the nuclear force that binds the quarks together.
* carry the strong force between other quarks , so it is considered a force carrying particle
  - nuclear force that binds together the quarks in a neutron
* have color charge themselves and so gluons interact with gluons
  - one color and one anti-color
  - two colors, one normal color and one anti-color
* serve the function of carrying color when they interact with quarks.
  * carry the strong force between other quarks, so it is considered a force carrying particle. Photons do the same thing, but for the electromagnetic force.
+ Strong interaction, Fundamental/ Color Strong Force: Force :: Nuclear physics :: Basic physics ideas
  * Like the electromagnetic force, opposite colors attract, and the same colors repel. Some particles that have color charge are quarks and antiquarks. The type of quark is not related to that quark's color charge at all. This is in fact because the nature of the strong force between particles is that it becomes stronger the further away the particles are. The force carrier of the strong force is the gluon. Gluons also have color charge. Both quarks and gluons have properties that make them unique from other particles.

Graviton
* Most gravitons exist in a cloud around the object.
* are no longer the fundamental mediators of the gravitational interaction
  - still a hypothesis of quantum mechanics
* can behave as particles.
* have a double ended arrow next to their fuel tankage.

### substance | particle | boson:

Meson
* All mesons are unstable, with the longest-lived lasting for only a few hundredths of a microsecond.
* also are bosons.
* are a family of composite particles which are made of one quark and one antiquark
  - combinations of two quarks
  - essentially a quark and an antiquark, bound transiently by the strong interaction field
  - hadrons , which simply means that they are made of quarks
  - quark-antiquark pairs
  - subatomic particles composed of one quark and one antiquark
* consist of a coloured quark plus and antiquark with the corresponding anticolour.
* tend to be quark-antiquark pairs with very short lifetimes.
+ J/ψ particle
+ Meson, Mesons' spin: Quantum mechanics :: Subatomic particles
  * Mesons are hadrons, which simply means that they are made of quarks. Since quarks have different fractional charges, mesons can have a charge. However, the charges of the quarks may cancel out, forming an uncharged meson. The rest of the hadron family are known as baryons, which are made of three quarks. Particles with an integer spin are called bosons, which obey Bose-Einstein Statistics. This means that more than one boson can actually be in the same point in space at the same time.

Pion
* are elementary particles
  - particles that consist primarily of a quark and an anti-quark
  - short-lived particles primarily responsible for the nuclear force
* decay into muons and neutrinos, which both come out of the end of the pipe
  - to produce muons and muon-type neutrinos
