3HDM with symmetry and its phenomenological consequences
J. Kalinowski, W. Kotlarski, M. N. Rebelo +1
We perform a comprehensive analysis of a version of the 3-Higgs doublet model whose scalar potential is invariant under a global discrete symmetry and where the three scala…
Decays of the Heavy Top and New Insights on in a one-VLQ Minimal Solution to the CKM Unitarity Problem
Francisco J. Botella, G. C. Branco, M. N. Rebelo +2
We propose a minimal extension of the Standard Model where an up-type vector-like quark, denoted , is introduced and provides a simple solution to the CKM unitarity problem. We…
Dark matter in three-Higgs-doublet models with symmetry
W. Khater, A. Kunčinas, O. M. Ogreid +2
Models with two or more scalar doublets with discrete or global symmetries can have vacua with vanishing vacuum expectation values in the bases where symmetries are imposed. If a s…
Diluting quark flavor hierarchies using dihedral symmetry
Ayushi Srivastava, Miguel Levy, Dipankar Das
We present a flavored extension of the SM which provides an intuitive reasoning for the masses and mixing patterns in the quark sector. In our model, the Cabibbo mixing angle…
Prospects of light charged scalars in a three Higgs doublet model with symmetry
Manimala Chakraborti, Dipankar Das, Miguel Levy +2
The stringent constraints from the direct searches for exotic scalars at the LHC as well as indirect bounds from flavor physics measurements have imposed severe restrictions on the…
Addressing the CKM Unitarity Problem with a Vector-like Up Quark
G. C. Branco, J. T. Penedo, Pedro M. F. Pereira +2
We point out that hints of deviations from unitarity in the first row of the CKM matrix may be explained by the presence of a single vector-like top. We study how the stringent exp…
Leaks of CP violation in the real two-Higgs doublet model
Duarte Fontes, Maximilian Löschner, Jorge C. Romão +1
We discuss the symmetric two Higgs doublet model with a real soft breaking term (real 2HDM). We explain in detail why it is not tenable to assume CP conservation in the scala…
