The Electroweak Phase Transition in the MSSM

  title={The Electroweak Phase Transition in the MSSM},
  author={Marta Losada},
The construction of an effective 3D theory at high temperatures for the MSSM as a model of electroweak baryogenesis is discussed. The analysis for a single light scalar field shows, that given the experimental constraints, there is no value of the Higgs mass for which a sufficiently strong first-order phase transition is obtained. A precise determination of the 3D parameters of the effective theory for the case of a light right-handed stop allows us to obtain an upper bound on the masses of the… CONTINUE READING
