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…

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…

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…
