Tree-unitarity bounds for THDM Higgs masses revisited
J. Horejsi, M. Kladiva
We have reconsidered theoretical upper bounds on the scalar boson masses within the two-Higgs-doublet model (THDM), employing the well-known technical condition of tree-level unita…
Possible non-decoupling effects of heavy Higgs bosons in e+ e- -> W+ W- within THDM
Michal Malinsky, Jiri Horejsi
We discuss the origin of the nondecoupling effects of the heavy Higgs bosons within the two Higgs doublet extension (THDM) of the Standard Model (SM) and illustrate it by means of…
Contribution of dimension-six bosonic operators to Higgs decay into two photons at one-loop level
Jiri Horejsi, Karol Kampf
The decay of the Higgs boson into two photons is examined in a model-independent way within the effective Lagrangian approach. Contribution of one-loop diagrams including SU(2) x U…
Triple gauge vertices at one-loop level in THDM
Michal Malinsky, Jiri Horejsi
Renormalized triple gauge vertices (TGV) are examined within the two-Higgs-doublet model of electroweak interactions. Deviations of the TGV from their standard-model values are cal…
