Effective Theories of Mssm at High Temperature
We construct effective 3d field theories for the Minimal Supersymmetric Standard Model, relevant for the thermodynamics of the cosmological electroweak phase transition. The effective theories include a 3d theory for the bosonic sector of the original 4d theory; a 3d two Higgs doublet model; and a 3d SU(2)+Higgs model. The inte-grations are made at 1-loop level. In integrals related to vacuum r...
متن کاملFlavour Geometry and Effective Yukawa Couplings in the MSSM
We present a new geometric approach to the flavour decomposition of an arbitrary soft supersymmetry-breaking sector in the MSSM. Our approach is based on the geometry that results from the quark and lepton Yukawa couplings, and enables us to derive the necessary and sufficient conditions for a linearly-independent basis of matrices related to the completeness of the internal [SU(3) ⊗ U(1)] flav...
متن کاملThe post-Higgs MSSM scenario: habemus MSSM?
We analyze the Minimal Supersymmetric extension of the Standard Model that we have after the discovery of the Higgs boson at the LHC, the hMSSM (habemus MSSM?), i.e. a model in which the lighter h boson has a mass of approximately 125 GeV which, together with the non-observation of superparticles at the LHC, indicates that the SUSY-breaking scale MS is rather high, MS ≳1 TeV. We first demonstra...
متن کاملMixing Effects in the Finite-Temperature Effective Potential of the MSSM with a Light Stop
We incorporate the effects of mixing arising from the trilinear terms in the MSSM potential to the effective three dimensional theory for the MSSM at high temperature in the limit of large mA. There are relevant one-loop effects that modify the 3D parameters of the effective theory. We calculate the two-loop effective potential of the 3D theory for the Higgs and the right handed stop to analyse...
متن کاملEffective potential methods and the Higgs mass spectrum in the MSSM ∗
We generalize the analytical expressions for the two-loop leading-log neutral Higgs boson masses and mixing angles to the case of general left-and right-handed soft supersymmetry breaking stop and sbottom masses and left– right mixing mass parameters (m Q , m U , m D , A t , A b). This generalization is essential for the computation of Higgs masses and couplings in the presence of light stops. ...
