Abstract

In the Minimal Supersymmetric Standard Model (MSSM) searches for the heaviest CP-even and CP-odd Higgs $H$ , $A$ to tau-lepton pairs severely constrain the parameter region for large values of $tan β$ and light Higgs bosons $H$ , $A$ . We demonstrate how the experimental constraint can be avoided by new decays to light third-generation sfermions, whose left-right couplings to $H$ can be maximised in regions of large trilinear couplings $A_{b}$ , $A_{τ}$ for sbottoms and staus, or large supersymmetric (SUSY) Higgs mass $μ$ for stops. Due to the $tan β$ -enhancement in the production cross-sections via gluon-fusion and in association with bottom-quark pairs for $H$ and $A$ , we find that down-type sfermions, in particular, sbottoms perform a better job in allowing more parameter space than up-type sfermions such as stops, which require much larger values of $μ$ to compensate for $tan β$ . Vacuum stability as well as flavour observables constraints and direct searches for SUSY particles are imposed. We also associate the lightest CP-even Higgs with the observed 125 GeV SM-like Higgs and impose the experimental constraints from the LHC.
