Classes of complete dark photon models constrained by Z-Physics
Miguel P. Bento, Howard E. Haber, João P. Silva
Dark Matter models that employ a vector portal to a dark sector are usually treated as an effective theory that incorporates kinetic mixing of the photon with a new U(1) gauge boso…
The Basis Invariant Flavor Puzzle
Miguel P. Bento, Joao P. Silva, Andreas Trautner
The flavor puzzle of the Standard Model quark sector is formulated in a non-perturbative way, using basis invariants that are independent of the choice of quark field basis. To ach…
Tree-level Unitarity in SU(2)U(1)U(1) Models
Miguel P. Bento, Howard E. Haber, João P. Silva
In models with a U(1) gauge extension beyond the Standard Model, one can derive sum rules for the couplings of the theory that are a consequence of tree-level unitarity. In this pa…
The invariant space of multi-Higgs doublet models
M. P. Bento
In a model with more than one scalar doublet, the parameter space encloses both physical and unphysical information. Invariant theory provides a detailed description of the countin…
A fully basis invariant Symmetry Map of the 2HDM
Miguel P. Bento, Rafael Boto, João P. Silva +1
We derive necessary and sufficient conditions for all global symmetries of the most general two Higgs doublet model (2HDM) scalar potential entirely in terms of reparametrization i…
Multi-Higgs doublet models: the Higgs-fermion couplings and their sum rules
Miguel P. Bento, Howard E. Haber, J. C. Romao +1
This is the second of a series of papers that explores the physical parameterization, sum rules and unitarity bounds arising from a non-minimal scalar sector of the Standard Model…
