Higgs phenomenology of supersymmetric economical 3-3-1 model
We explore the Higgs sector in the supersymmetric economical 3-3-1 model and
find new features in this sector. The charged Higgs sector is revised i.e., in
difference of the previous work, the exact eigenvalues and states are obtained
without any approximation. In this model, there are three Higgs bosons having
masses equal to that of the gauge bosons--the W and extra X and Y. There is one
scalar boson with mass of 91.4 GeV, which is closed to the boson mass and
in good agreement with present limit: 89.8 GeV at 95% CL. The condition of
eliminating for charged scalar tachyon leads to splitting of VEV at the first
symmetry breaking, namely, . The interactions among the
standard model gauge bosons and scalar fields in the framework of the
supersymmetric economical 3-3-1 model are presented. From these couplings, at
some limit, almost scalar Higgs fields can be recognized in accordance with the
standard model. The hadronic cross section for production of the bilepton
charged Higgs boson at the CERN LHC in the effective vector boson approximation
is calculated. Numerical evaluation shows that the cross section can exceed
35.8 fb.Comment: 33 pages, 1 figur
