Phenomenology of the minimal B - L extension of the standard model: The Higgs sector

We investigate the phenomenology of the Higgs sector of the minimal B - L extension of the standard model. We present results for both the foreseen energy stages of the Large Hadron Collider (root s = 7 and 14 TeV). We show that in such a scenario several novel production and decay channels involving the two physical Higgs states could be accessed at such a machine. Amongst these, several Higgs signatures have very distinctive features with respect to those of other models with an enlarged Higgs sector, as they involve interactions of Higgs bosons between themselves, with Z' bosons as well as with heavy neutrinos.
