For particle physicists, the search for such a soup provides a way of testing one of their most fundamental theories: that of quantum chromodynamics (QCD).
Mathematical procedures that work in QED cannot be used in QCD.
These problems were resolved by the introduction of the concept of colour, as formulated in quantum chromodynamics (QCD).
This phenomenon became known as asymptotic freedom, and it led to a completely new physical theory, quantum chromodynamics (QCD), to describe the strong force.
During the mid-1970s much work was done toward developing quantum chromodynamics (QCD), a gauge theory of the interactions between quarks (see quark).
In the theory of the strong force known as quantum chromodynamics (QCD), eight quanta, called gluons, bind quarks to form baryons and also bind quarks to antiquarks to form mesons, the force itself being dubbed the "colour force".
The discovery of this phenomenon, known as asymptotic freedom, led to a completely new physical theory, quantum chromodynamics (QCD), to describe the strong force.
Quantum chromodynamics (QCD), in physics, the theory that describes the action of the strong force.
This phenomenon became known as asymptotic freedom, and it led to a new physical theory, quantum chromodynamics (QCD), to describe the strong force.
While electroweak theory allows extremely precise calculations to be made, problems arise with the theory of the strong force, quantum chromodynamics (QCD), despite its similar structure as a gauge theory.
The theory (QCD) predicted that in a certain fraction of these diet events, one of the quarks would radiate a gluon with enough energy to form its own jet.
