A type of sub-atomic particle, quarks are thought to be the most elementary of particles.
A type of ub-atomic particle.
The basic constituent particles of the proton, neutron, pion and stranger relatives. Interact via the strong nuclear force. They also come in six types (flavours): up and down, strange and charm, bottom and top, with increasing masses.
Quarks are combined to form hadrons - Six types of quarks: up, down, charm, strange, top and bottom
A fundamental constituent of matter generally found in protons and neutrons. To date, six quarks are known and termed; up, down, strange, charm, bottom, and top.
Any of six fractionally charged elementary particle that experience the strong force and that appear to exist only in combinations of two or three. There are also six corresponding anti-quarks.
Fundamental particles, incapable of independent existence, that combine to form particles such as protons and neutrons.
elementary particles that supposedly come in pairs.
an elementary particle; a building block of protons and neutrons.
Subatomic particles which possess a fractional electric charge, and of which protons, neutrons, and other hadrons are believed to be composed.
Subparticle units that form the elementary particles. There are several species of quarks, each of which possesses, in addition to mass and electric charge, other fundamental attributes such as c-charge (color) and f-charge (flavor).
According to particle physics these sub-atomic particles are believed to be the constituents of elementary particles known as hadrons. Five or possibly six different sorts are thought to exist, but new discoveries are being made all the time.
