When a gluon is transferred between quarks, a color change occurs in both; for example, if a red quark emits a red—antigreen gluon, it becomes green, and if a green quark absorbs a red—antigreen gluon, it becomes red.
Therefore, while each quark's color constantly changes, their strong interaction is preserved. Since gluons carry color charge, they themselves are able to emit and absorb other gluons.
This causes asymptotic freedom : as quarks come closer to each other, the chromodynamic binding force between them weakens.
The color field becomes stressed, much as an elastic band is stressed when stretched, and more gluons of appropriate color are spontaneously created to strengthen the field.
Above a certain energy threshold, pairs of quarks and antiquarks are created. These pairs bind with the quarks being separated, causing new hadrons to form.
This phenomenon is known as color confinement : quarks never appear in isolation. The only exception is the top quark, which may decay before it hadronizes.
Hadrons contain, along with the valence quarks q v that contribute to their quantum numbers , virtual quark—antiquark q q pairs known as sea quarks q s.
Sea quarks form when a gluon of the hadron's color field splits; this process also works in reverse in that the annihilation of two sea quarks produces a gluon.
The result is a constant flux of gluon splits and creations colloquially known as "the sea". Despite this, sea quarks can hadronize into baryonic or mesonic particles under certain circumstances.
Under sufficiently extreme conditions, quarks may become "deconfined" out of bound states and propagate as thermalized "free" excitations in the larger medium.
In the course of asymptotic freedom , the strong interaction becomes weaker at increasing temperatures. Eventually, color confinement would be effectively lost in an extremely hot plasma of freely moving quarks and gluons.
This theoretical phase of matter is called quark—gluon plasma. The exact conditions needed to give rise to this state are unknown and have been the subject of a great deal of speculation and experimentation.
An estimate puts the needed temperature at 1. The quark—gluon plasma would be characterized by a great increase in the number of heavier quark pairs in relation to the number of up and down quark pairs.
Given sufficiently high baryon densities and relatively low temperatures — possibly comparable to those found in neutron stars — quark matter is expected to degenerate into a Fermi liquid of weakly interacting quarks.
This liquid would be characterized by a condensation of colored quark Cooper pairs , thereby breaking the local SU 3 c symmetry.
Because quark Cooper pairs harbor color charge, such a phase of quark matter would be color superconductive ; that is, color charge would be able to pass through it with no resistance.

Archived from the original on 22 January From to , an accelerator called HERA Hadron-Elektron Ring Anlage in Hamburg scattered other subatomic particles — electrons — off protons at very high energies, and made very direct measurements of those quarks and gluons.
Once you have taken those into account, the quark should look the same, no matter how closely you look. Unexpected changes in the cross section could be a sign that we are beginning to see a finite non-zero size for the quark.
Having spent a long time understanding their data — in particular, in understanding how the quarks and gluons are distributed inside the proton — the ZEUS experiment has just released a new limit on the size of the quark.
It is, as one might expect, very small indeed. August 20th, 15 Comments. What is snow? Weather — Earth science. What causes the seasons? Earth science.

Much smaller. Quarks are fundamental particles, and three quarks make up protons and neutrons, which in turn make up atoms.
The particle is called the "Quark". Yes, a proton is built from two up-quarks and one down-quark. There are 3 parts to an atom: 1.
Protons 2. Neutrons 3. Electrons The electrons are the smallest of the 3 and therefor weigh the least. A proton is composed of 2 up quarks and 1 down quark while a neutron is composed of 1 up quark and 2 down quarks.
The Up Quark weighs more than the Down quark. Therefore, the proton would weigh more. See Photon exhange to see how an Up quark turns in a Down quark through photon exchange.
A quark is a fundamental subatomic particle, or class of subatomic particles. It is smaller than an atom. The nucleus of an atom contains protons and neutrons, which are comprised of up and down quarks.
The proton contains two up quarks and one down quark, while the neutron contains one up quark and two down quarks. When we think about the Nucleus of an Atom it is made up with Neutrons and Protons.
Whilst Protons have two Up quarks and one Down quark. So we can see that the Nucleus of an Atom is not only made up but dependent on Up and Down quarks.
