Towards a renormalizable standard model without fundamental Higgs scalar
Holger Gies, Joerg Jaeckel, Christof Wetterich
We investigate the possibility of constructing a renormalizable standard model with purely fermionic matter content. The Higgs scalar is replaced by point-like fermionic self-inter…
Chemical Freeze-out and the QCD Phase Transition Temperature
P. Braun-Munzinger, J. Stachel, C. Wetterich
We argue that hadron multiplicities in central high energy nucleus-nucleus collisions are established very close to the phase boundary between hadronic and quark matter. In the had…
Critical Phenomena in Continuous Dimension
H. Ballhausen, J. Berges, C. Wetterich
We present a calculation of critical phenomena directly in continuous dimension d employing an exact renormalization group equation for the effective average action. For an Ising-t…
First Order Chiral Phase Transition from a Six-fermion ''Instanton''-Interaction
Joerg Jaeckel, Christof Wetterich
We compute the first order chiral phase transition for an instanton motivated quark model with a local six-quark interaction. In order to compare different solutions of the gap equ…
Temperature dependence of antiferromagnetic order in the Hubbard model
T. Baier, E. Bick, C. Wetterich
We suggest a method for an approximative solution of the two dimensional Hubbard model close to half filling. It is based on partial bosonisation, supplemented by an investigation…
Antiferromagnetic gap in the Hubbard model
T. Baier, E. Bick, C. Wetterich
We compute the temperature dependence of the antiferromagnetic order parameter and the gap in the two dimensional Hubbard model at and close to half filling. Our approach is based…
