A Higgs boson near 125 GeV with enhanced di-photon signal in the NMSSM
Ulrich Ellwanger
A natural region in the parameter space of the NMSSM can accomodate a CP-even Higgs boson with a mass of about 125 GeV and, simultaneously, an enhanced cross section times branchin…
Benchmark Models, Planes, Lines and Points for Future SUSY Searches at the LHC
S. S. AbdusSalam, B. C. Allanach, H. K. Dreiner +11
We define benchmark models for SUSY searches at the LHC, including the CMSSM, NUHM, mGMSB, mAMSB, MM-AMSB and p19MSSM, as well as models with R-parity violation and the NMSSM. With…
Higgs Bosons in the Next-to-Minimal Supersymmetric Standard Model at the LHC
Ulrich Ellwanger
We review possible properties of Higgs bosons in the NMSSM, which allow to discriminate this model from the MSSM: masses of mostly Standard-Model-like Higgs bosons at or above 140…
Naturalness and Fine Tuning in the NMSSM: Implications of Early LHC Results
Ulrich Ellwanger, Gregory Espitalier-Noel, Cyril Hugonie
We study the fine tuning in the parameter space of the semi-constrained NMSSM, where most soft Susy breaking parameters are universal at the GUT scale. We discuss the dependence of…
NMSDECAY: A Fortran Code for Supersymmetric Particle Decays in the Next-to-Minimal Supersymmetric Standard Model
Debottam Das, Ulrich Ellwanger, Ana M. Teixeira
The code NMSDECAY allows to compute widths and branching ratios of sparticle decays in the Next-to-Minimal Supersymmetric Standard Model. It is based on a generalization of SDECAY,…
Reduced branching ratio for H -> AA -> 4 tau from A - eta_b mixing
Florian Domingo, Ulrich Ellwanger
Models with an extended Higgs sector, as the NMSSM, allow for scenarios where the Standard Model-like CP-even Higgs boson H decays dominantly as H -> AA -> 4 tau where A is a light…
