Chaotic behavior of confining lattice gauge field configurations

Tamas S. Biro, Markus Feurstein, Harald Markum

We analyze the leading Lyapunov exponents of SU(2) Yang-Mills field configurations on the lattice which are initialized by quantum Monte Carlo simulations. We find that configurati…

Casimir Scaling from Center Vortices: Towards an Understanding of the Adjoint String Tension

M. Faber, J. Greensite, S. Olejnik

We argue that the approximate ``Casimir scaling'' of the string tensions of higher-representation Wilson loops is an effect due to the finite thickness of center vortex configurati…

On the D*D and B*B coupling constants in the effective quark model with chiral symmetry

A. N. Ivanov, N. I. Troitskaya

The coupling constants of D*D and B*B strong interactions are computed in the effective quark model with chiral symmetry incorporating Heavy quark effective theory (HQET) and…

Exact Path Integral Quantization of 2-D Dilaton Gravity

W. Kummer, H. Liebl, D. V. Vassilevich

We demonstrate that in the absence of `matter' fields to all orders of perturbation theory and for all 2D dilaton theories the quantum effective action coincides with the classical…

Nambu-Jona-Lasinio approach to realization of confining medium

M. Faber, A. N. Ivanov, N. I. Troitskaya

The mechanism of a confining medium is investigated within the Nambu-Jona-Lasinio (NJL) approach. It is shown that a confining medium can be realized in the bosonized phase of the…

On the - nonresonant decay in the effective quark model with chiral symmetry

A. N. Ivanov, N. I. Troitskaya

The partial widths of the decays and - nonresonant are computed within the effective quark model with chiral symmetry involving Heavy quark…
