In the context of the Supersymmetric (SUSY) B-L (Baryon minus Lepton number) model with an inverse seesaw mechanism, we calculate the one-loop radiative corrections due to right-handed (s)neutrinos to the mass of the lightest Higgs boson when the latter is Standard Model (SM)-like. We show that such effects can be as large as O(100) GeV, thereby giving an absolute upper limit on such a mass around 200 GeV. The importance of this result from a phenomenological point of view is twofold. On the one hand, this enhancement greatly reconciles theory and experiment, by alleviating the so-called `little hierarchy problem' of the minimal SUSY realization, whereby the current experimental limit on the SM-like Higgs mass is very near its absolute upper limit predicted theoretically, of 130 GeV. On the other hand, a SM-like Higgs boson with mass below 200 GeV is still well within the reach of the Large Hadron Collider (LHC), so that the SUSY realization discussed here is just as testable as the minimal version.
