NMSSM with correct relic density and an additional 95 GeV Higgs boson
Ulrich Ellwanger, Cyril Hugonie
We investigate whether it is possible within the NMSSM to describe simultaneously a correct dark matter relic density complying with the latest null results from the LZ experiment,…
NMSSM Explanation for Excesses in the Search for Neutralinos and Charginos and a 95 GeV Higgs Boson
Ulrich Ellwanger, Cyril Hugonie, Stephen F. King +1
The observed excesses in the search for neutralinos and charginos by ATLAS and CMS can be fitted simultaneously in the minimal supersymmetric standard model (MSSM) assuming a light…
Benchmark Lines and Planes for Higgs-to-Higgs Decays in the NMSSM
Ulrich Ellwanger, Margarete Muehlleitner, Nikolaos Rompotis +2
A number of benchmark scenarios for NMSSM Higgs boson searches via Higgs-to-Higgs decays at the LHC have been proposed by the NMSSM Subgroup of the LHC HWG3. Some of them are alrea…
Additional Higgs Bosons near 95 and 650 GeV in the NMSSM
Ulrich Ellwanger, Cyril Hugonie
Hints for an additional Higgs boson with a mass of about 95 GeV originate from LEP and searches in the diphoton channel by CMS and ATLAS. A search for resonant production of SM plu…
Benchmark Planes for Higgs-to-Higgs Decays in the NMSSM
Ulrich Ellwanger, Cyril Hugonie
We present benchmark planes (or lines) with cross sections via gluon fusion for the processes , resonant Higgs pair and triple Higgs production, $A \to h+(A_S \to γγ)…
Gradient Flow and Holography from a Local Wilsonian Cutoff
Ulrich Ellwanger
We consider the vacuum partition function of a 4d scalar QFT in a curved background as function of bare marginal and relevant couplings. A local UV cutoff transforming under…
