Complementarity of gravitational wave analyses and di-Higgs production in the exploration of the Electroweak Phase Transition dynamics in the RxSM
Johannes Braathen, Sven Heinemeyer, Carlos Pulido Boatella +1
The real singlet extension of the Standard Model (SM), RxSM, is one of the simplest Beyond-the-Standard Model (BSM) theories that can accommodate a strong first-order electroweak p…
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…
Refining two-loop corrections to trilinear Higgs couplings in the Two-Higgs-Doublet Model
Johannes Braathen, Felix Egle, Alain Verduras Schaeidt
The precise determination of the Higgs self-couplings is an essential task for understanding electroweak symmetry breaking and probing physics beyond the Standard Model (SM). The c…
Precision predictions for trilinear scalar couplings and Higgs pair production in models with extended scalar sectors
Johannes Braathen
Reconstructing the shape of the Higgs potential realised in Nature is one of the most pressing tasks of current and future colliders. This will offer deep insights into the dynamic…
Precise predictions for trilinear Higgs couplings and Higgs pair production in extended scalar sectors with anyH3 and anyHH
Henning Bahl, Johannes Braathen, Martin Gabelmann +2
A central objective of future collider experiments is to probe the structure of the Higgs potential, which requires access to trilinear scalar couplings, in particular the self-cou…
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…
