Renormalization-Group-Improved Effective Potential for the MSSM Higgs Sector with Explicit CP Violation
We perform a systematic study of the one-loop renormalization-group-improved effective potential of the minimal supersymmetric extension of the Standard Model (MSSM), including CP violation induced radiatively by soft trilinear interactions related to squarks of the third generation. We calculate the charged and neutral Higgs-boson masses and couplings, including the two-loop logarithmic correc...
متن کاملMass bounds of the lightest CP-even Higgs boson in the two-Higgs-doublet model
The upper and the lower bounds of the lightest CP-even Higgs-boson mass (mh) are discussed in the two-Higgs-doublet model (2HDM) with a softly-broken discrete symmetry. They are obtained as a function of a cut-off scale Λ (≤ 10 GeV) by imposing the conditions in which the running coupling constants neither blow up nor fall down below Λ. In comparison with the standard model (SM), although the u...
متن کاملOn distinguishing the direct and spontaneous CP violation in 2HDM
The most general Two Higgs Doublet Model (2HDM) allows both for the explicit and the spontaneous CP violation in the scalar sector. Here we discuss CP violation in terms of basisindependent quantities and show how using two different sets of known CP-odd weak-basis invariants one can distinguish between CP conservation, explicit CP violation and spontaneous CP violation. The special case of CP ...
متن کاملF = 2 processes in the MSSM in large tan β limit
We discuss corrections to ∆M B d , ∆M Bs and to the CP violation parameter ε in two examples of (generalized) minimal flavour violation models: 2HDM and MSSM in the large tan β limit. We show that for H + not too heavy, ∆M Bs in the MSSM with heavy sparticles can be substantially smaller than in the SM due the charged Higgs box contributions and in particular due to the growing like tan 4 β con...
متن کاملCP–violating Chargino Contributions to the Higgs Coupling to Photon Pairs in the Decoupling Regime of Higgs Sector
In most supersymmetric theories, charginos χ̃±1,2 belong to the class of the lightest supersymmetric particles and the couplings of Higgs bosons to charginos are in general complex so that the CP–violating chargino contributions to the loop–induced coupling of the lightest Higgs boson to photon pairs can be sizable even in the decoupling limit of large pseudoscalar mass mA with only the lightest...
