  The effective Lagrangian with scalar and vector resonances that might result
from new strong physics beyond the SM is formulated and studied. In particular,
the scalar resonance representing the recently discovered 125-GeV boson is
complemented with the SU(2)_{L+R} triplet of hypothetical vector resonances.
Motivated by experimental and theoretical considerations, the vector resonance
is allowed to couple directly to the third quark generation only. The coupling
is chiral-dependent and the interaction of the right top quark can differ from
that of the right bottom quark. To estimate the applicability range of the
effective Lagrangian the unitarity of the gauge boson scattering amplitudes is
analyzed. The experimental fits and limits on the free parameters of the vector
resonance triplet are investigated.
