quarks

Usually the discussion is about if it's really a pentaquark particle with 5 quarks, or it's only a baryon with 3 quarks traveling along with a meson with 2 quarks.

Every neutron has 2 Down quarks and 1 Up quark (UDD); every proton has 1 Down quark and 2 Up quarks (UUD).

Down quarks are more energetic (massive) than Up quarks.

The standard model was constructed to contain mesons (2 quarks) and hadrons (3 quarks), so the discovery of tetra and pentaquarks is a rather stringent test for predictions of the SM.

Nuclei with an odd number of nucleons (protons and neutrons) would have to have an even number of quarks.

There may be something to the number of quarks, research into that is difficult because the act of pulling quarks apart requires so much energy that it just creates new quarks.

The underlying mechanics are highly theoretical, but it has something to do with the quarks that compose protons and neutrons.

As the Big Bang cooled quarks eventually cooled down enough to make protons and neutrons.

Wherever you go, you will find females far less likely than males to see what is so fascinating about ohms, carburetors, or quarks.

What about things like the Quarks used in the Galileo and the Edison?

Protons and neutrons are themselves made of up more elementary quantum particles: quarks!

For example, electrical charge is discrete, not continuous, and the unit appears to be 1/3 the charge on the electron (as carried by quarks).

As such, beancounters insist on running that "cost" until it has been ground into component quarks...

There might be a "final" explanation in the sense that we talk about quarks, strings, etc.

Sometimes in the field of physics "matter" is simply equated with particles that exhibit rest mass (i.e., that cannot travel at the speed of light), such as quarks and leptons.

Quarks have themselves mass, but they can also have mass as part of their field.
