Flavor 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 ...

Quark Confinement and Deconfinement Transition in Large Flavor QCD

We give a new criterion of quark confinement/deconfinement by deriving a low-energy effective theory of QCD. The effective theory can explain Abelian dominance in low-energy physics of QCD, especially, quark confinement. Finally, we apply the above criterion to the large flavor QCD and discuss its phase structure. The result suggests the existence of conformal phase.

Possible Hadronic Molecule Λ(1405) and Thermal Glueballs in SU(3) Lattice QCD

We aim to construct quark hadron physics based on QCD. First, using lattice QCD, we study mass spectra of positive-parity and negative-parity baryons in the octet, the decuplet and the singlet representations of the SU(3) flavor. In particular, we consider the lightest negative-parity baryon, the Λ(1405), which can be an exotic hadron as theNK̄ molecular state or the flavor-singlet three-quark s...

Data 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...

The role of Lattice QCD in flavor physics

Understanding flavor physics is one of the most important tasks of particle physics today, which is motivating an extraordinary experimental and theoretical investigational effort. Important progress in this field has already been achieved in the last few years, with Lattice QCD calculations playing an essential role in this effort. I will describe some lattice contributions to the studies of f...
