Models of The QCD Vacuum
A full solution of QCD would automatically give a full description of the vacuum, confinement and the hadron spectrum. Lattice QCD is making rapid progress towards providing the solution as a systematically improvable numerical computation. However, approximate models of the QCD vacuum remain useful in more restricted domains. The purpose of these models is to make quantitative sense of some set of condensates and hadron properties such as masses and form factors.
This section is devoted to models. Opposed to these are systematically improvable computational procedures such as large N QCD and lattice QCD, which are described in their own articles.

Famous quotes containing the words models of, models and/or vacuum:
“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
—Marshall McLuhan (1911–1980)
“Grandparents can be role models about areas that may not be significant to young children directly but that can teach them about patience and courage when we are ill, or handicapped by problems of aging. Our attitudes toward retirement, marriage, recreation, even our feelings about death and dying may make much more of an impression than we realize.”
—Eda Le Shan (20th century)
“When a daughter tries suicide
and the chimney falls down like a drunk
and the dog chews her tail off
and the kitchen blows up its shiny kettle
and the vacuum cleaner swallows its bag
and the toilet washes itself in tears ...”
—Anne Sexton (1928–1974)
