The Phase Diagram of Three-Dimensional SU(3) + Adjoint Higgs Theory
K. Kajantie, M. Laine, A. Rajantie +2
We study the phase diagram of the three-dimensional SU(3)+adjoint Higgs theory with lattice Monte Carlo simulations. A critical line consisting of a first order line, a tricritical…
Higgs sector CP-violation at the electroweak phase transition
M. Laine, K. Rummukainen
We consider explicit and spontaneous CP-violation related to the profile of the two Higgs doublets at the MSSM electroweak phase transition. We find, in accordance with previous re…
Light hadron spectrum with Kogut-Susskind quarks
MILC Collaboration, C. Bernard, C. DeTar +7
We made an extensive study of the light hadron spectrum using the Wilson gauge action and Kogut-Susskind quarks. Using both dynamical quarks and the quenched approximation, we dete…
What's new with the electroweak phase transition?
M. Laine, K. Rummukainen
We review the status of non-perturbative lattice studies of the electroweak phase transition. In the Standard Model, the complete phase diagram has been reliably determined, and th…
Vortex tension as an order parameter in three-dimensional U(1)+Higgs theory
K. Kajantie, M. Laine, T. Neuhaus +3
We use lattice Monte Carlo simulations to study non-perturbatively the tension, i.e. the free energy per unit length, of an infinitely long vortex in the three-dimensional U(1)+Hig…
Gauge-invariant strings in the 3d U(1)+Higgs theory
K. Kajantie, M. Laine, T. Neuhaus +3
We describe how the strings, which are classical solutions of the continuum three-dimensional U(1)+Higgs theory, can be studied on the lattice. The effect of an external magnetic f…
