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 hightemperature
SU(N) YangMills theory, EQCD, will considerably
extend its applicability towards the deconfinement
transition. In this talk, I will discuss the construction
of such centersymmetric 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 nonperturbative
matching of the parameters of the effective theory,
and outline ways to further improve its description
of the physics near the deconfinement transition.
