Ring diagrams and electroweak phase transition in a magnetic field
Apr, 1999Citations per year
Abstract:
Electroweak phase transition in a magnetic field is investigated within the one-loop and ring diagram contributions to the effective potential in the minimal Standard Model. All fundamental fermions and bosons are included with their actual values of masses and the Higgs boson mass is considered in the range . The effective potential is real at sufficiently high temperature. The important role of fermions and -bosons in symmetry behaviour is observed. It is found that the phase transition for the field strengths G is of first order but the baryogenesis condition is not satisfied. The comparison with the hypermagnetic field case is done.- electroweak interaction: critical phenomena
- magnetic field: external field
- Feynman graph: higher-order
- effective potential
- fermion: mass
- boson: mass
- Higgs particle: mass
- temperature
- numerical calculations
