Anomaly-free 2HDMs with a gauged abelian symmetry and two generations of right-handed neutrinos
Astrid Ordell, Roman Pasechnik, Hugo Serôdio
Despite the popularity of two-Higgs-doublet models (2HDMs) with a gauged abelian flavor symmetry, the allowed Yukawa textures have only been partly explored so far. In this work, w…
Classification of anomaly-free 2HDMs with a gauged U(1)' symmetry
Astrid Ordell, Roman Pasechnik, Hugo Serôdio +1
Two-Higgs-doublet models (2HDMs) with a flavored U(1)' gauge symmetry are a popular extension to the Standard Model (SM), yet they currently lack a complete survey. In this paper,…
CP4 miracle: shaping Yukawa sector with CP symmetry of order four
P. M. Ferreira, Igor P. Ivanov, Enrique Jiménez +2
We explore the phenomenology of a unique three-Higgs-doublet model based on the single CP symmetry of order 4 (CP4) without any accidental symmetries. The CP4 symmetry is imposed o…
Revealing timid pseudo-scalars with taus at the LHC
Giacomo Cacciapaglia, Gabriele Ferretti, Thomas Flacke +1
A light pseudo-scalar that is copiously produced at the LHC may still be allowed by present searches. While masses above 65 GeV are effectively covered by di-photon searches, the l…
Di-boson signatures as Standard Candles for Partial Compositeness
Alexander Belyaev, Giacomo Cacciapaglia, Haiying Cai +4
Composite Higgs Models are often constructed including fermionic top partners with a mass around the TeV scale, with the top partners playing the role of stabilizing the Higgs pote…
Maximally restrictive leptonic texture zeros in two-Higgs-doublet models
R. Gonzalez Felipe, H. Serodio
The implementation of maximally restrictive texture zeros in the leptonic sector is investigated in the context of two-Higgs-doublet models with Majorana neutrinos. After analyzing…
