Field distributions and static potential in baryon in the method of field correlators
نویسنده
چکیده
Distributions of the gluonic field and potential of three static sources are calculated in the framework of bilocal approximation of method of field correlators. The field in baryon is shown to be a sum of the fields of three mesonic strings, with the string junction and corresponding quarks acting like sources. The interference of fields of these mesonic strings near string junction position leads to depletion of the full field, and decreasing of the slope of static potential at small quark separations. Dependency of the potential on quark configurations is studied and conclusions on the probable configurations are made. Some contradictions in lattice simulations of static baryon potential are discussed.

Static potentials and confining field structure of baryons and 3g-glueballs
Static potentials in baryons and 3g-glueballs are calculated using the field correlator method. It is shown that the static baryon potential describes lattice data. For confining fields defined through the “connected probe” distributions in both types of hadrons are calculated. It is demonstrated that the structure of baryon is of Y type (but not the ∆-type one). A field distribution in ∆-type ...
متن کاملStatic potential in baryon in the method of field correlators
The static three-quark potential in arbitrary configuration of quarks is calculated analytically. It is shown to be in a full agreement with the precise numerical simulations in lattice QCD. The results of the work have important application in nuclear physics, as they allow to perform accurate analytic calculations of spectra of the baryons.

The baryon static potential is calculated in the framework of field correlator method and is shown to match the recent lattice results. The effects of the nonzero value of the gluon correlation length are emphasized. 1. The static potential is a key quantity in the calculations of spectra and wave functions of baryons in the potential models [1], as well as in the QCD string approach [2]. On th...
متن کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملTriangular and Y - shaped hadrons in QCD
Gauge invariant extended configurations are considered for the three fundamental (quarks) or adjoint (gluons) particles. For quarks it is shown that the Y-shaped configuration is the only possible. For adjoint sources both the Y-shaped and triangular configurations may realize. The corresponding static potentials are calculated in the Method of Field Correlators and in the case of baryon shown ...
