Investigating a strong first-order electroweak phase transition in the RxSM at future linear colliders and LISA
Johannes Braathen, Sven Heinemeyer, Carlos Pulido Boatella +1
The general real singlet extension of the Standard Model (SM), the RxSM, is one of the simplest theories Beyond-the-Standard Model (BSM) that can accommodate a strong first-order e…
Sensitivity to new physics: single-Higgs couplings vs. the trilinear Higgs coupling
Henning Bahl, Johannes Braathen, Martin Gabelmann +4
The trilinear Higgs self-coupling provides a unique probe of the structure of the Higgs potential and of the nature of the electroweak phase transition, and constitutes a key targe…
Pseudoscalar contributions to Zh production at the LHC at 95 GeV and above
J. Dutta, P. M. Ferreira, S. Heinemeyer
In generalizations of the Standard Models with extended scalar sectors, pseudoscalar particles will contribute to associated production of the Higgs boson discovered at the LHC, $h…
GUT-based NMSSM with Singlino Dark Matter: Describing the ATLAS/CMS Excesses
E. Bagnaschi, M. Chakraborti, S. Heinemeyer +1
One of the main goals of the ongoing LHC program is the search for BSM physics, with EW SUSY partners still allowed with masses as low as a few hundred GeV. Over the last years, se…
Consistent Excesses in the LHC Electroweak SUSY Searches: GUT-based Singlino/Higgsino Interpretation in the NMSSM
Emanuele Bagnaschi, Manimala Chakraborti, Sven Heinemeyer +1
The search for supersymmetric models remains one of the main items on the BSM search program at the LHC, with EW SUSY partners still allowed with masses as low as a few hundred GeV…
