Higgs-gauge boson interactions in the economical 3-3-1 model

Abstract

Interactions among the standard model gauge bosons and scalar fields in the framework of SU(3)_C X SU(3)_L X U(1)_X gauge model with minimal (economical) Higgs content are presented. From these couplings, all scalar fields including the neutral scalar $h$ and the Goldstone bosons can be identified and their couplings with the usual gauge bosons such as the photon, the charged $W^{\pm }$ and the neutral $Z$, without any additional condition, are recovered. In the effective approximation, full content of scalar sector can be recognized. The CP-odd part of Goldstone associated with the neutral non-Hermitian bilepton gauge boson $G_{X^0}$ is decouple, while its CP-even counterpart has the mixing by the same way in the gauge boson sector. Masses of the new neutral Higgs boson $H_1^0$ and the neutral non-Hermitian bilepton $X^0$ are dependent on a coefficient of Higgs self-coupling (${\lambda }_1$). Similarly, masses of the singly-charged Higgs boson $H_2^{\pm }$ and of the charged bilepton $Y^{\pm }$ are proportional through a coefficient of Higgs self-interaction (${\lambda }_4$). The hadronic cross section for production of this Higgs boson at the LHC in the effective vector boson approximation is calculated. Numerical evaluation shows that the cross section can exceed 260 $fb$.
