Interactions among the standard model gauge bosons and scalar fields in the framework of the SU(3){sub C}xSU(3){sub L}xU(1){sub 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{sup {+-}}, and the neutral Z, without any additional conditions, are recovered. In the effective approximation, the full content of the scalar sector can be recognized. The CP-odd part of the Goldstone associated with the neutral non-Hermitian bilepton gauge boson G{sub X{sup 0}} is decoupled, while its CP-even counterpart has the mixing in the same way in the gauge boson sector. Masses of the new neutral Higgs boson H{sub 1}{sup 0} and the neutral non-Hermitian bilepton X{sup 0} are dependent on a coefficient of Higgs self-coupling ({lambda}{sub 1}). Similarly, masses of the singly charged Higgs boson H{sub 2}{sup {+-}} and of the charged bilepton Y{sup {+-}} are proportional through a coefficient of Higgs self-interaction ({lambda}{sub 4}). The hadronic cross section for production of this Higgs boson at the CERN LHC in the effective vector boson approximation is calculated. Numerical evaluation shows that the cross section can exceed 260 fb.
