Very Heavy MSSM Higgs-Boson Production at the Linear Collider
In the Minimal Supersymmetric Standard Model (MSSM) we present the corrections to the heavy neutral CP-even Higgs-boson production in the WW -fusion and Higgs-strahlung channel, ee → ν̄ν H , taking into account all O(α) corrections arising from loops of fermions and sfermions. While the H boson shows decoupling behavior at the tree-level, we find non-negligible loop corrections that can enhance ...
متن کاملbackgrounds at the Next Linear Collider. 1
The complete matrix element for ee → bb̄WW has been computed at tree–level and applied to ZH production followed by Z → bb̄ and H → WW, keeping into account all irreducible backgrounds, which are dominated by tt̄ production, at the Next Linear Colliders. We find that, depending on the center of mass energies and on the search strategies, this channel can be useful for the study of the parameters o...
متن کاملSingle Charged Mssm Higgs-boson Production at a Linear Collider
In the Minimal Supersymmetric Standard Model we present the calculation of the single charged Higgs-boson production in the γW or ZW -fusion and the charged Higgs strahlung channel, ee → eνeH. The set of all O(α) corrections arising from loops of Standard Model fermions and scalar fermions are taken into account. Contrary to the case of single neutral heavy CP-even Higgs-boson production, for t...
متن کاملStudy of Higgs Boson Pair Production at Linear Collider
We study the potential of the TESLA linear collider operated at a center-of-mass energy of 500 to 1000 GeV for the measurement of the neutral Higgs boson properties within the framework of the MSSM. The process of associated Higgs boson production with subsequent decays of Higgs bosons into b-quark and τ -lepton pairs is considered. An integrated luminosity of 500 fb is assumed at each energy. ...
متن کاملHeavy charged Higgs boson production at next generation γγ colliders
We investigate the scope of all relevant production modes of charged Higgs bosons in the MSSM, with mass larger than the one of the top quark, at future Linear Colliders operating in γγ mode at the TeV energy scale. Final states with one or two H bosons are considered, as produced by both treeand loop-level interactions.
