High Temperature Behavior of the Chern-Simons Diffusion Rate in the 1+1 D Abelian Higgs Model
W. H. Tang, J. Smit
We give arguments that in the 1+1 dimensional abelian Higgs model the classical approximation can be good for the leading high temperature behavior of real time processes. The Cher…
Numerical study of plasmon properties in the SU(2)-Higgs model
W. H. Tang, J. Smit
Using the (effective) classical approximation, we compute numerically time-dependent correlation functions in the SU(2)-Higgs model around the electroweak phase transition, for $m_…
Fermion production despite fermion number conservation
Wolfgang Bock, James E. Hetrick, Jan Smit
Lattice proposals for a nonperturbative formulation of the Standard Model easily lead to a global U(1) symmetry corresponding to exactly conserved fermion number. The absence of an…
A Magnetic Monopole in Pure SU(2) Gauge Theory
J. Smit, A. J. Van Der Sijs
The magnetic monopole in euclidean pure SU(2) gauge theory is investigated using a background field method on the lattice. With Monte Carlo methods we study the mass of the monopol…
Chiral gauge theories on the lattice and restoration of gauge symmetry
Wolfgang Bock, Jan Smit, Jeroen C. Vink
We investigate a proposal for the construction of models with chiral fermions on the lattice using staggered fermions. In this approach the gauge invariance is broken by the coupli…
Computing the Mass of a Magnetic Monopole in SU(2) Gauge Theory
J. Smit, A. J. van der Sijs
A single magnetic monopole in pure SU(2) gauge theory is simulated on the lattice and its mass is computed in the full quantum theory. The results are relevant for our proposed rea…
