Electroweak phase transition by four dimensional simulations
نویسنده
چکیده
The finite temperature phase transition in the SU(2)-Higgs model at a Higgs boson mass MH ≃ 35 GeV is studied in numerical simulations on four dimensional lattices with time-like extensions up to Lt = 5. Tc/MH is extrapolated to the continuum limit and a comparison with the perturbative prediction is made. A one-loop calculation to the coupling anisotropies of the SU(2)-Higgs model on lattices with asymmetric lattice spacings is presented. Our numerical simulations show that the above perturbative result is applicable in the phenomenologically interesting parameter region.

متن کاملFour-dimensional lattice results on the MSSM electroweak phase transition
We present the results of our large scale 4-dimensional (4d) lattice simulations for the MSSM electroweak phase transition (EWPT). We carried out infinite volume and continuum limit extrapolations and found a transition whose strength agrees well with perturbation theory. We determined the properties of the bubble wall that are important for a successful baryogenesis.
متن کاملFour-dimensional Simulation of the Hot Electroweak Phase Transition with the SU(2) Gauge-Higgs Model
We study the finite-temperature electroweak phase transition of the minimal standard model within the four-dimensional SU(2) gauge-Higgs model. Monte Carlo simulations are performed for intermediate values of the Higgs boson mass in the range 50 ∼ MH ∼ 100GeV on a lattice with the temporal size Nt = 2. The order of the transition is systematically examined using finite-size scaling methods. Beh...

The finite temperature phase transition in the SU(2) Higgs model at a Higgs boson mass MH ≃ 34 GeV is studied in numerical simulations on four-dimensional lattices with time-like extensions up to Lt = 5. The effects of the finite volume and finite lattice spacing on masses and couplings are studied in detail. The errors due to uncertainties in the critical hopping parameter are estimated. The t...
متن کاملElectroweak phase transition: recent results
Recent results of four-dimensional (4d) lattice simulations on the finite temperature electroweak phase transition (EWPT) are discussed. The phase transition is of first order in the SU(2)-Higgs model below the end point Higgs mass 66.5±1.4 GeV. For larger masses a rapid cross-over appears. This result completely agrees with the results of the dimensional reduction approach. Including the full ...

We study the finite temperature electroweak phase transition with lattice perturbation theory and Monte Carlo techniques. Dimensional reduction is used to approximate the full four-dimensional SU(2) + a fundamental doublet Higgs theory by an effective three-dimensional SU(2) + adjoint Higgs + fundamental Higgs theory with coefficients depending on temperature via screening masses and mass count...
