Avoiding Death by Vacuum
A. Barroso, P. M. Ferreira, I. Ivanov +2
The two-Higgs doublet model (2HDM) can have two electroweak breaking, CP-conserving, minima. The possibility arises that the minimum which corresponds to the known elementary parti…
Tree-level metastability bounds in two-Higgs doublet models
A. Barroso, P. M. Ferreira, I. Ivanov +1
The two Higgs doublet model has a rich vacuum structure, including the possibility of existence of two Standard Model-like minima at tree-level. It is therefore possible that the u…
2HDM at the LHC - the story so far
A. Barroso, P. M. Ferreira, Rui Santos +2
We confront the most common version of the CP-conserving 2HDM with LHC data, taking into account all previously available experimental data. We also discuss the scenario where the…
Metastability bounds on the two Higgs doublet model
A. Barroso, P. M. Ferreira, I. P. Ivanov +1
In the two Higgs doublet model, there is the possibility that the vacuum where the universe resides in is metastable. We present the tree-level bounds on the scalar potential param…
Evading death by vacuum
A. Barroso, P. M. Ferreira, I. P. Ivanov +2
In the Standard Model, the Higgs potential allows only one minimum at tree-level. But the open possibility that there might be two scalar doublets enriches the vacuum structure, al…
Probing the scalar-pseudoscalar mixing in the 125 GeV Higgs particle with current data
A. Barroso, P. M. Ferreira, Rui Santos +1
LHC has found hints for a Higgs particle of 125 GeV. We investigate the possibility that such a particle is a mixture of scalar and pseudoscalar states. For definiteness, we concen…
