NLO electroweak corrections in general scalar singlet models
Raul Costa, Marco O. P. Sampaio, Rui Santos
If no new physics signals are found, in the coming years, at the Large Hadron Collider Run-2, an increase in precision of the Higgs couplings measurements will shift the dicussion…
Singlet Extensions of the Standard Model at LHC Run 2: Benchmarks and Comparison with the NMSSM
Raul Costa, Margarete Mühlleitner, Marco O. P. Sampaio +1
The Complex singlet extension of the Standard Model (CxSM) is the simplest extension that provides scenarios for Higgs pair production with different masses. The model has two inte…
Two-loop stability of singlet extensions of the SM with dark matter
Raul Costa, António P. Morais, Marco O. P. Sampaio +1
We present a study of the high energy stability of a minimal complex singlet extension of the Standard Model with or without dark matter (CxSM). We start by obtaining the beta func…
Two-loop stability of a complex singlet extended Standard Model
Raul Costa, António P. Morais, Marco O. P. Sampaio +1
Motivated by the dark matter and the baryon asymmetry problems, we analyse a complex singlet extension of the Standard Model (SM) with a Z2 symmetry (which provides a dark matter c…
