Unreferenced date September 2009 A constituent quark is a current quark with a covering. In the low energy limit of Quantum chromodynamics QCD , a description by means of perturbation theory is not possible. Here, no Asymptotic freedom exists, but the interactions between valence quark s and sea quark s gain strongly on significance. Part of the effects of virtual quark s and virtual gluon s in the sea can be assigned to a quark so well that the term constituent quark seems appropriate. According to the Feynman diagram s, constituent quarks seem to be dressed current quarks, i.e. current quarks surrounded by a cloud of virtual quarks and gluons. This cloud in the end explains the large constituent quark masses. Definition Constituent quarks are valence quarks for which the correlations for the description of hadrons by means of gluons and sea quarks are put into effective quark masses of these valence quarks. The effective quark mass is called constituent quark mass . Hadrons consist of glued constituent quarks. The use of positions for the light constituent quarks is not exactly unproblematic in the description of hadrons. Binding energy The quantum chromodynamic binding energy of a valence quark in a hadron is the amount of energy required to make the hadron spontaneously emit a meson containing the valence quark. This is the same as the constituent quark mass. class wikitable Constituent quark Mass x Up quark val 308 ul MeV c2 Citation needed date March 2011 val 0.7 ul fm Citation needed date March 2011 Downquark val 308 ul MeV c2 Citation needed date March 2011 val 0.7 ul fm Citation needed date March 2011 Strange quark val 483 ul MeV c2 Citation needed date March 2011 Charm quark Bottom quark Top quark Describing hadrons using non relativistic quantum mechanics becomes difficult.

Current quarks also called naked quarks or bare quarks are defined as the constituent quark cores constituent quarks with no covering of a valence quark . ref Smith, Timothy Paul Hidden Worlds Hunting for Quarks in Ordinary Matter 2003 ref If, in one constituent quark, the current quark is hit inside the covering with large force, it accelerates through the covering and leaves it behind. In addition, current quarks possess one asymptotic freedom within the perturbation theory described limits.

The Quark was first displayed at the 2004 Paris Motor Show . It utilises hydrogen fuel cell s and has an electric motor on each of the four wheel s. All four motors combined give the Quark 30 kW or 40 horsepower hp . It can drive approximately convert 130 km mi before it requires refueling. The Quark is convert 2.38 m in long and convert 1.50 m in wide. The empty weight is convert 450 kg lb 0 abbr on and its top speed is convert 110 km h mph 0 abbr on . It can accelerate to convert 50 km h mph 0 abbr on in 6.5 seconds, and can carry two people with an additional load of convert 140 kg lb 0 abbr on . Although it may look like an All terrain vehicle ATV , it is considerably larger and not designed for true Off roading off road conditions. Because of its low ground clearance and short range, it would be more suitable for short trips in the city. Though the Quark received praise by many because of its exotic and unusual design, the Quark in its current form will not go into production. It does give a glimpse of what we might expect from Peugeot in the future however, especially when the fuel cell technology powering the vehicle has been perfected. It can now be seen in Paris at the Cit des Sciences et de l Industrie on the second floor of its exhibition site.

Physical cosmology In physical cosmology the quark epoch was the period in the evolution of the early universe when the fundamental interaction s of gravitation , electromagnetism , the strong interaction and the weak interaction had taken their present forms, but the temperature of the universe was still too high to allow quark s to bind together to form hadron s. The quark epoch began approximately 10 sup 12 sup seconds after the Big Bang , when the preceding electroweak epoch ended as the electroweak interaction separated into the weak interaction and electromagnetism. During the quark epoch the universe was filled with a dense, hot quark gluon plasma , containing quarks, leptons and their antiparticles. Collisions between particles were too energetic to allow quarks to combine into meson s or baryon s. The quark epoch ended when the universe was about 10 sup 6 sup seconds old, when the average energy of particle interactions had fallen below the binding energy of hadrons. The following period, when quarks became confined within hadrons, is known as the hadron epoch .
