Z and Higgs Factory Implications of Two Higgs Doublets with First-Order Phase Transitions
Anisha, Francisco Arco, Stefano Di Noi +2
We investigate the potential of future electron-positron colliders, such as FCC-ee and CEPC, to probe 2-Higgs-doublet models (2HDMs) that facilitate a strong first-order electrowea…
Top-quark spin correlations as a tool to distinguish pseudoscalar and scalar signatures in final states at the LHC
Francisco Arco, Thomas Biekötter, Panagiotis Stylianou +1
Both ATLAS and CMS have recently performed the first searches for a heavy new spin-0 resonance decaying into a lighter new spin-0 resonance and a boson, where the lighter spin-…
Large One-Loop Effects of BSM Triple Higgs Couplings on Double Higgs Production at Colliders
F. Arco, S. Heinemeyer, M. Mühlleitner
The measurement of the Higgs boson self-coupling is crucial for our understanding of the nature of electroweak symmetry breaking and potential physics beyond the Standard Model (BS…
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…
