Suppressing gravitino thermal production with a temperature-dependent messenger coupling
Marcin Badziak, Ioannis Dalianis, Zygmunt Lalak
We show that the constraints on GMSB theories from the gravitino cosmology can be significantly relaxed if the messenger-spurion coupling is temperature dependent. We demonstrate t…
Interpreting the 750 GeV diphoton excess in minimal extensions of Two-Higgs-Doublet models
Marcin Badziak
It is shown that the 750 GeV diphoton excess can be explained in extensions of Two-Higgs-Doublet Models that do not involve large multiplicities of new electromagnetically charged…
Blind spots for neutralino dark matter in the NMSSM
Marcin Badziak, Marek Olechowski, Paweł Szczerbiak
Spin-independent cross-section for neutralino dark matter scattering off nuclei is investigated in the NMSSM. Several classes of blind spots for direct detection of singlino-Higgsi…
Gauge Mediation in the NMSSM with a Light Singlet: Sparticles within the Reach of LHC Run II
Ben Allanach, Marcin Badziak, Cyril Hugonie +1
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 coupl…
Detecting underabundant neutralinos
Marcin Badziak, Antonio Delgado, Marek Olechowski +2
The electroweak sector may play a crucial role in discovering supersymmetry. We systematically investigate the patterns of the MSSM-like electroweakinos, when the neutralino relic…
Light Sparticles from a Light Singlet in Gauge Mediation
B. C. Allanach, M. Badziak, C. Hugonie +1
We revisit a simple model that combines minimal gauge mediation and the next-to-minimal supersymmetric standard model. We show that one can obtain a 125 GeV Standard Model-like Hig…
