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…

Impact of one-loop corrections to trilinear scalar couplings on di-Higgs production in the RxSM

Johannes Braathen, Sven Heinemeyer, Andrea Parra Arnay +1

We investigate di-Higgs production at the (HL-)LHC and possible high-energy future colliders within the real Higgs singlet extension of the Standard Model (SM), the RxSM.…

Sensitivity to Triple Higgs Couplings via Di-Higgs Production in the RxSM at the (HL-)LHC and future Colliders

F. Arco, S. Heinemeyer, M. Mühlleitner +3

The real Higgs singlet extension of the Standard Model (SM) without symmetry, the RxSM, is the simplest extension of the SM that features a First Order Electroweak Phase Tran…
