A new lattice measurement for potentials between static SU(3) sources
In this article, a new calculation of static potentials between sources of
different representations in SU(3) gauge group is presented. The results of
author's previous study \cite{Deld00} at the smallest lattice spacing
~ fm are shown to have been affected by finite volume effects.
Within statistical errors, the new results obtained here are still in agreement
with both, Casimir scaling and flux tube counting. There is also no
contradiction to the results obtained in Ref.~ \cite{Bali00} which however
exclude flux counting.Comment: To be published in EPJ
Partition Function of Interacting Calorons Ensemble
We present a method for computing the partition function of a caloron
ensemble taking into account the interaction of calorons. We focus on
caloron-Dirac string interaction and show that the metric that Diakonov and
Petrov offered works well in the limit where this interaction occurs. We
suggest computing the correlation function of two polyakov loops by applying
Ewald's method.Comment: Contribution to the XIth conference Quark Confinement and the Hadron

Flux tube counting or Casimir scaling
QCD confines quarks in all representations. From lattice calculations and fat
center vortices model, we discuss that the coefficient of the linear term in
the potential is proportional to both casimir scaling and the number of
fundamental strings.Comment: 3 pages, 4 figures, talk given by S. Deldar at 6th Conference on

The Interaction of Two Dyons in The Near Field Limit
We study the interaction of two dyons in the region of their cores where they
are non-linear and non-Abelian. We assume the superposition of two dyons as a
solution of the equation of motion. The terms due to the non-linearity of the
strength tensor are considered as the perturbation terms which deforms the
profile function of two individual dyons. As a result, the profile function of
dyons are obtained to be dependent on the polar angle and the spherical
symmetry is lost
