      The Σ0–Λ mixing angle in isospin-asymmetric nuclear medium is investigated by using QCD sum rules. From the general consideration of the in-medium bar. The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non-perturbative vacuum state [further explanation needed], characterized by non-vanishing condensates such as the gluon condensate and the quark condensate in the complete theory which includes quarks. The presence of these condensates characterizes the confined phase of quark matter.

      Hadronic condensates play an important role in quantum chromodynamics. Two important examples are and, where q is a light quark (i.e., a quark with current quark mass small compared with the quantum chromodynamics (QCD) scale Λ QCD),, a, b, c are color indices, and N c = 3. (For most of the paper we focus on QCD at zero temperature and chemical potential, T = μ = 0.). Direct instanton contributions are found to strongly dominate over those from perturbative fluctuations and soft vacuum fields. All IOPE sum rules, including the one involving a subtraction.

    QCD dynamics. In the case of two-point sum rules, these parameters are the averag ed local densities of the QCD vacuum elds, the condensates. The contributions of vac-uum e ects in OPE are suppressed by inverse powers of the large momentum and/or heavy-quark mass scale, allowing one to truncate the expansion at some maxima l power.

The method of the QCD sum rules was and still is one of the most productive tools in a wide range of problems Vacuum structure and QCD sum rules book with the hadronic phenomenology.

In fact, the Volume Vacuum Structure and QCD Sum Rules (North-Holland, Amsterdam, ) of which I was the editor, was the tenth and the last in the series. 2The list of references is slightly updated. 3Also known as the Shifman{Vainshtein{Zakharov (SVZ for short) sum rules.

Abstract This note was written as an introduction to the volume Vacuum Structure and QCD Sum Rules (North-Holland, ). It has never been published. Three major issues — the structure of the QCD vacuum, the structure of hadrons, and the physics of hot/dense matter — are addressed as physics problems.

Therefore, when discussing any specific subject, the book attempts to incorporate (1) all the solid theoretical results, (2) experimental information, and (3) results of numerical (lattice. Especially the vacuum state of the quantum theory of strong interactions (QCD) has an incredibly rich structure and there are lots of things that are happening.

In fact, there is so much going on, that the vacuum isn’t fully understood yet. Structure of the QCD Vacuum: brief survey.

Pre-Coulombic behavior Baryons Form factors at intermediate Q2 These methods are based on the operator product expansion and ascend to the SVZ sum rules elaborated 20 years ago. They allow one to relate a large variety of properties of the low-lying hadronic states and important regularities established in the hadronic world to a few vacuum condensates parametrizing the vacuum of quantum chromodynamics.

Vacuum condensates are very important in the elucidation ofthe QCD structure and in description of hadron properties at low energies. Condensates, particularly, quark and gluonic ones, were investigated starting from the ties.

Here, first, it should be noted the QCD sum rule method by Shifman. the analytical QCD sum rules are to a large extent complementary to the nu-merical lattice simulations of hadrons.

It is a very special occasion to write a review on QCD sum rules in honor of B.L. Io e who contributed to this eld with landmark results, considerably enlarging the spectrum of hadronic problems treated within this method.

In the QCD sum rules, the operator product expansion is used to expand the time-ordered currents into a series of quark and gluon condensates which parameterize the long distance properties of the QCD vacuum.

Based on the quark-hadron duality, we can obtain copious information about the hadronic parameters at the phenomenological side [6, 7.

For now, Dürr’s calculation shows that QCD describes quark-based particles accurately, and tells us that most of our mass comes from virtual quarks and gluons fizzing away in the quantum vacuum.Vacuum Structure and QCD Sum Rules.
