Resumen:
We study the phenomenology of the light and heavy Higgs boson production and
decay in the context of a U (1)B-L extension of the standard model with an
additional Z' boson at future e+ e- linear colliders with center-of-mass energies of
s = 500–3000 GeV and integrated luminosities of L= 500 - 2000 fb^-1.
The study includes the processes e+ e- --> (Z, Z') --> Zh and
e+ e- --> (Z, Z') --> ZH, considering both the resonant and non-resonant effects.
We find that the total number of expected Zh and ZH events can reach 909, 124
and 97, 487, respectively, which is a very optimistic scenario and thus it would be
possible to perform precision measurements for both Higgs bosons h and H, as
well as for the Z' boson in future high-energy and high-luminosity e+e- colliders
experiments. Our study complements other studies on the B–L model and on the
Higgs-strahlung processes e+e- --> (Z, Z') --> Zh and e+ e- -->(Z, Z') --> ZH.
