Aleksi Kurkela (Zurich):
Dimensional reduction near the deconfinement transition
Abstract:
It is expected
that incorporating the center symmetry in the conventional
dimensionally reduced effective theory for high-temperature
SU(N) Yang-Mills theory, EQCD, will considerably
extend its applicability towards the deconfinement
transition. In this talk, I will discuss the construction
of such center-symmetric effective theories and
present results from their lattice simulations in
the case of two colors. The simulations demonstrate
that unlike EQCD, the new center symmetric theory
undergoes a second order confining phase transition
in complete analogy with the full theory. I will
also describe the perturbative and non-perturbative
matching of the parameters of the effective theory,
and outline ways to further improve its description
of the physics near the deconfinement transition.
