Effective Z(2) Spin Models of Deconfinement and Percolation in SU(2) Gauge Theory
S. Fortunato, F. Karsch, P. Petreczky +1
Effective theories are helpful tools to gain an intuitive insight into phenomena governed by complex laws. In this work we show by means of Monte Carlo simulations that Z(2) spin m…
Percolation and Critical Behaviour in SU(2) Gauge Theory
S. Fortunato, F. Karsch, P. Petreczky +1
The paramagnetic-ferromagnetic transition in the Ising model can be described as percolation of suitably defined clusters. We have tried to extend such picture to the confinement-d…
Screening in Hot SU(2) Gauge Theory and Propagators in 3d Adjoint Higgs model
A. Cucchieri, F. Karsch, P. Petreczky
We investigate the large distance behavior of the electric and magnetic propagators of hot SU(2) gauge theory in different gauges using lattice simulations of the full 4d theory an…
Magnetic Screening in Hot Non-Abelian Gauge Theory
A. Cucchieri, F. Karsch, P. Petreczky
We analyze the large distance and low-momentum behavior of the magnetic gluon propagator of the SU(2) gauge theory at finite temperature. Lattice calculations within the 4-dimensio…
