Spontaneous P-parity violation in dense baryon matter
S. S. Afonin, A. A. Andrianov, V. A. Andrianov +1
We investigate possibilities for dynamical P-parity violation in dense baryon matter in the framework of effective quark models. Dynamical P-parity violation can appear in models w…
On the possibility of P-violation at finite baryon-number densities
A. A. Andrianov, D. Espriu
We show how the introduction of a finite baryon density may trigger spontaneous parity violation in the hadronic phase of QCD. Since this involves strong interaction physics in an…
Chiral Bosonization of U_A(1)-currents and the Energy-Momentum Tensor in Quantum Chromodynamics
A. A. Andrianov, V. A. Andrianov, V. L. Yudichev
Recently the new interest arised (hep-ph/0403139) to the chiral coefficients in the low-energy ChPT lagrangian describing the pseudoscalar meson coupling t…
QCD tests for Quasilocal Quark Model
A. A. Andrianov, V. A. Andrianov, S. S. Afonin
We perform the QCD testing of the Quasilocal Quark Model (QQM) based on Operator Product Expansion (OPE). The quark current correlators calculated in framework of the model, are co…
Vector mesons in Quasilocal Quark Models
A. A. Andrianov, V. A. Andrianov, S. S. Afonin
We consider the Quasilocal Quark Model of NJL type including vector and axial-vector four-fermion interaction with derivatives. In the presence of a strong attraction in the scalar…
Effective Quark Models in QCD at low and intermediate energies
A. A. Andrianov, V. A. Andrianov, D. Espriu +1
The effective quark models are employed to describe the hadronization of QCD in the quark sector. They reveal a different structure depending on how the spontaneous chiral symmetry…
