Abstract
We reconsider the lambda-SUSY model, in which the mass of the Higgs boson is raised already at tree level up to about 200 GeV via an additional interaction in the superpotential between the Higgs bosons and a Singlet, focusing on a scale invariant superpotential. After a detailed analysis of the allowed region in parameter space, which includes constraints coming from the absence of spontaneous CP violation and of unrealistic minima, we study the scalar mass spectrum, the production rate and the decay modes of the lightest scalar, finding that in general both the production rate and the Branching Ratio into gauge bosons can be reduced with respect of those of the standard Higgs, causing it to be hardly detected in the first run of the LHC.
