Abstract

We consider recent experimental limits on the scalar bosons in the λSUSY framework, in which the masses of the scalar particles are increased already at tree level via a largish supersymmetric coupling between the usual Higgs doublets and a singlet. We analyze in particular the two lightest scalars, discussing the regions of parameter space excluded by LHC data.
