Unifying cosmological and recent time variations of fundamental couplings
Thomas Dent, Steffen Stern, Christof Wetterich
A number of positive and null results on the time variation of fundamental constants have been reported. It is difficult to judge whether or not these claims are mutually consisten…
Chiral tensor fields and spontaneous breaking of Lorentz symmetry
Jan-Markus Schwindt, Christof Wetterich
Antisymmetric tensor fields interacting with quarks and leptons have been proposed as a possible solution to the gauge hierarchy problem. We compute the one-loop beta function for…
Light fermion masses and chiral freedom
Christof Wetterich
Within the scenario of chiral freedom we compute the quark and lepton masses of the first two generations in terms of their chiral couplings. This allows us to make a rough estimat…
Do Instantons Like a Colorful Background?
Holger Gies, Joerg Jaeckel, Jan M. Pawlowski +1
We investigate chiral symmetry breaking and color symmetry breaking in QCD. The effective potential of the corresponding scalar condensates is discussed in the presence of non-pert…
Chiral freedom and electroweak symmetry breaking
C. Wetterich
Antisymmetric tensor fields with chiral couplings to quarks and leptons may induce spontaneous electroweak symmetry breaking in a model without a ``fundamental'' Higgs scalar. No m…
Higgs picture of the QCD-vacuum
C. Wetterich
The functional integral for QCD is reformulated by introducing explicitly an integration over the fluctuations of composite quark-antiquark bound states. Chiral symmetry breaking b…
