Analytic determination of the T-μphase diagram of the chiral quark model
A. Jakovac, A. Patkos, Zs. Szep +1
Using a gap equation for the pion mass a nonperturbative method is given for solving the chiral quark-meson model in the chiral limit at the lowest order in the fermion contributio…
Effect of the scalar condensate on the linear gauge field response in the Abelian Higgs model
A. Jakovac, A. Patkos, Zs. Szep
The effective equations of motion for low-frequency mean gauge fields in the Abelian Higgs model are investigated in the presence of a scalar condensate, near the high temperature…
Beyond HTL: The Classical Kinetic Theory of Landau Damping for Selfinteracting Scalar Fields in the Broken Phase
A. Patkos, Zs. Szep
The effective theory of low frequency fluctuations of selfinteracting scalar fields is constructed in the broken symmetry phase. The theory resulting from integrating fluctuations…
QCD thermodynamics from 3d adjoint Higgs model
F. Karsch, M. Oevers, A. Patkos +2
The screening masses of hot SU(N) gauge theory, defined as poles of the corresponding propagators are studied in 3d adjoint Higgs model, considered as an effective theory of QCD, u…
Effective Models of the Electroweak Phase Transition
A. Patkós
The consecutive integration over the distinct mass scales leads to a hierarchy of effective models for the electroweak phase transition. Different techni…
