9. Einstein equation for nondual field matter modifies Naiver-Stocks dynamics

Igor Bulyzhenkov (MIPT, Moscow)

Talk

Continuous material space in the nondual field physics of Einstein and Infeld replaces the assumed emptiness between point particles in the Newton model of reality. The internal heat of circular metric flows creates the elementary mass-energy and this kinetic energy is balanced by the negative self-gravitation energy. The Einstein equation analog for nonequilibrium field densities of moving...

10. SU(2)-Gluon Propagators and the $A_\mu^2$ Asymmetry in the Postconfinement Domain

Roman Rogalyov (IHEP, Protvino)

Talk

We study numerically the chromoelectric-chromomagnetic asymmetry of the dimension two $A^2$ gluon condensate as well as the {\it transverse and longitudinal} gluon propagators at $T>T_c$ in the Landau-gauge $SU(2)$ lattice gauge theory with a particular emphasis on finite-volume effects. We show that previously found so called symmetric point at which asymmetry changes sign is an artifact of...

4. Dipole polarizabilities of pi+- meson

Lev Fil'kov (LPI, Moscow)

Talk

The main experimental works, where dipole polarizabilities of charged pions have been determined, are discussed. Possible reasons for the differences between the experimental data are considered. In particular, it is shown that the account of the $\sigma$-meson gives a significant correction to the value of the polarizability obtained in the latest experiment of the COMPASS collaboration.

26. Charged pion condensation in chirally asymmetric dense quark matter: Consideration of an NJL2 model with spatially inhomogeneous condensates

Roman Zhokhov ( IHEP, Protvino)

05/07/2017, 17:25

Talk

In this talk we investigate the phase structure of a (1+1)-dimensional schematic quark model with four-quark interaction and in the presence of baryon (µB), isospin (µI) and chiral isospin (µI5) chemical potentials. Spatially inhomogeneous chiral density wave (for chiral condensate) and single wave (for charged pion condensate) approaches are used. It is established that in the large-Nc limit...

12. Colour particle states behaviour in the QCD vacuum

Viacheslav Kuvshinov (JIPNRS NAS, Minsk, Belarus)

Talk

To study the properties of colour particle states behaviour in the QCD vacuum we calculate the density matrix of the system colour particle - stochasticQCD vacuum, considered as environment, and averaged over degrees of freedom of the environment.As a result the density matrix of colour particle is depended on the Wilson loop which depends on spanned area RT. In the stochastic vacuum Wilson...
