An Abelian two-Higgs model and high temperature superconductivity
M. N. Chernodub, Arwed Schiller, E. -M. Ilgenfritz
We study a three dimensional Abelian Higgs model containing singly- and doubly-charged scalar fields coupled to a compact Abelian gauge field in the London limit. The model attract…
Embedded vortices and their interactions at electroweak crossover
M. N. Chernodub, E. -M. Ilgenfritz, A. Schiller
We study properties of Z-vortices in the crossover region of the 3D SU(2) Higgs model. Correlators of the vortex currents with gauge field energy and Higgs field squared ("quantum…
Dynamics of Topological Defects in Electroweak Theory
M. N. Chernodub, F. V. Gubarev, E. -M. Ilgenfritz +1
Embedded defects proposed long ago (Z-vortices and Nambu monopoles) have been successfully searched for in 3D equilibrium lattice studies within the standard model near the electro…
Comment on the absence of Coulomb effects on pair production in ultrarelativistic heavy-ion collisions
D. Yu. Ivanov, A. Schiller, V. G. Serbo
In recent works [Segev,Wells; Baltz, McLerran; Eichmann, Reinhardt, Schramm, Greiner] it was claimed that the Coulomb correction to the production cross section in relativ…
Improvement for Quenched Wilson Fermions
S. Capitani, M. Goeckeler, R. Horsley +9
We briefly describe some of our recent results for the mass spectrum and matrix elements using improved fermions for quenched QCD. Where possible a comparison is made betwee…
Hot Electroweak Matter Near to the Critical Higgs Mass
M. Gürtler, E. -M. Ilgenfritz, A. Schiller +1
We discuss the end of the first order phase transition and the bound state spectrum, both at weak transition and at the crossover.
