Quantum Chromodynamics - Theory

Theory

List of unsolved problems in physics
QCD in the non-perturbative regime:
  • Confinement: the equations of QCD remain unsolved at energy scales relevant for describing atomic nuclei. How does QCD give rise to the physics of nuclei and nuclear constituents?
  • Quark matter: the equations of QCD predict that a plasma (or soup) of quarks and gluons should be formed at high temperature and density. What are the properties of this phase of matter?

Famous quotes containing the word theory:

    “The great tragedy of science—the slaying of a beautiful theory by an ugly fact.”
    —Thomas Henry Huxley (1825–1895)

    “If my theory of relativity is proven correct, Germany will claim me as a German and France will declare that I am a citizen of the world. Should my theory prove untrue, France will say that I am a German and Germany will declare that I am a Jew.”
    —Albert Einstein (1879–1955)

    “There could be no fairer destiny for any physical theory than that it should point the way to a more comprehensive theory in which it lives on as a limiting case.”
    —Albert Einstein (1879–1955)
