Properties of Qcd Vacuum from Lattice
نویسنده
چکیده
1) Solid evidence exists that dual superconductivity 1,2,3 is the mechanism of colour confinement. 2) The Witten-Veneziano 6,7 formula for the mass of the η is definitely correct. This statement has been made possible by the construction of an improved (almost perfect) operator for the topological charge density. By use of the same technical improvement a detailed study of the topological susceptibility across the deconfining transition has been made, showing a sharp drop of it at Tc. 9

Structure of the QCD Vacuum As Seen By Lattice Simulations
This talk is a review of our studies of instantons and their properties as seen in our lattice simulations of SU(2) gauge theory. We have measured the topological susceptibility and the size distribution of instantons in the QCD vacuum. We have also investigated the properties of quarks moving in instanton background field configurations, where the sizes and locations of the instantons are take...
متن کاملData Envelopment Analysis from simulation on the Lattice QCD using CCR model
One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
متن کاملFlavor singlet phenomena in lattice QCD
Flavor singlet combinations of quark operators OΓ S = ūΓu+ d̄Γd+ s̄Γs contribute to many important physical observables in the low energy region of QCD. Experimentally one finds the values of some of these observables to be in sharp contrast to the naive (perturbative) theoretical expectations. This indicates that non perturbative vacuum properties might play a major role in the comprehension of ...

متن کاملExistence of Chiral-Asymmetric Zero Modes in the Background of QCD-Monopoles
There are two distinct pictures of the vacuum structure in QCD. One is based on the appearance of color-magnetic monopoles (QCDmonopoles) after performing the abelian gauge xing [1]. The recent lattice QCD simulations show that the dual Meissner e ect brought to the QCD vacuum by QCD-monopole condensation [2]. Hence, color con nement could be regarded as the dual version of the superconductivit...
متن کاملDilute Liquid of Instanton and Its Topological Charge Dominate the QCD Vacuum
APE smearing and overlap-Dirac operator are combined to filter QCD vacuum configurations. The results obtained from overlap fermions and improved 5Li cooling are compared, both of them exhibit structures of dilute liquid of instanton. Finally the overlap fermions, improved 5Li cooling and APE smearing are combined to calculate the topological charge and identify the structure of QCD vacuum. The...
