dc.description.abstract | Relatively light stops in gauge mediation models are usually made compatible
with the Higgs mass of 125 GeV by introducing direct Higgs-messenger couplings.
We show that such couplings are not necessary in a simple and predictive model
that combines minimal gauge mediation and the next-to-minimal supersymmetric
standard model (NMSSM). We show that one can obtain a 125 GeV Standard
Model-like Higgs boson with stops as light as 1.1 TeV, thanks to the mixing of
the Higgs with a singlet state at ${\cal O}(90-100)$ GeV that can explain the
LEP excess. In this scenario the singlet-higgs-higgs superfields coupling
$\lambda$ is small and $\tan\beta$ large. Sparticle searches at the LHC may
come with additional $b-$jets or taus and may involve displaced vertices. The
sparticle production cross-section at the 13 TeV LHC can be ${\mathcal
O}(10-100)$ fb, leading to great prospects for discovery in the early phase of
LHC Run II. | |
