  • Sh. Mamedov
چکیده

The motion of quark is studied in a confining bag having central color field. The Dirac equation is solved for a quark in such bag and its energy spectrum is found. It is pointed out the possibility to take into account an interaction of constituent quark with the gluon condensation as the interaction with the color background.

The motion of quark is studied in a confining bag having central color field. The Dirac equation is solved for a quark in such bag and its energy spectrum is found. It is pointed out the possibility to identify the external color field with the background field of gluon condensation. This makes the received energy spectrum of quark useful for comparison with the energy spectrum of hadrons.

We confront lattice QCD results on the transition from the hadronic phase to the quark–gluon plasma with hadron resonance gas and percolation models. We argue that for T ≤ Tc the equation of state derived from Monte–Carlo simulations of (2+1) quark–flavor QCD can be well described by a hadron resonance gas. We examine the quark mass dependence of the hadron spectrum on the lattice and discuss i...

The constant background bag model of the hadron

We have constructed the bag model having a central constant color field. The motion of the quark is studied in this bag and the Dirac equation is solved for it. The energy spectrum found has a branching due to the interaction of the quarks with the color background. It is pointed out that this model can be applied for taking into account, in mass spectrum of the hadrons, the coupling of the con...

Mass spectra of ground state hadrons containing u-, d-, s-, c-quarks as well as some lightest hadrons containing b-quarks are calculated on the basis of a slightly modified bag model. The center-of-mass motion corrections are incorporated using a wavepacket projection with Gaussian parametrization of the distribution amplitude. We use running coupling constant and also allow the effective quark...

We report on the first large-scale study of two flavor QCD with domain wall fermions (DWF). Simulation has been carried out at three dynamical quark mass values about 1/2, 3/4, and 1 mstrange on 16 3 × 32 volume with Ls = 12 and a −1 ≈ 1.7 GeV. After discussing the details of the simulation, we report on the light hadron spectrum and decay constants.
