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…
A viable 3HDM theory of quark mass matrices
Iris Bree, Sergio Carrolo, Jorge C. Romao +1
It is known that a three Higgs doublet model (3HDM)symmetric under an exact symmetry is not compatible with nonzero quark masses and/or non-block-diagonal CKM matrix. We show…
BFB conditions on a class of symmetry constrained 3HDM
Rafael Boto, Jorge C. Romão, João P. Silva
We study the bounded from below (BFB) conditions on a class of three Higgs doublet models (3HDM) constrained by the symmetry groups U(1)xU(1), U(1)xZ2 and Z2xZ2. These constraints…
Conditions for global minimum in the A4 symmetric 3HDM
Sergio Carrolo, Jorge C. Romao, Joao P. Silva
There has been a great interest in three Higgs doublet models (3HDM) symmetric under an exact A4 symmetry. We provide the complete analytic necessary and sufficient conditions for…
Unitarity bounds for all symmetry-constrained 3HDMs
Miguel P. Bento, Jorge C. Romão, João P. Silva
Models with three Higgs doublets (3HDM) are the source of much recent activity, for they are key components of many solutions to the problems of the Standard Model; from extra sour…
Current bounds on the Type-Z three Higgs doublet model
Rafael Boto, Jorge C. Romão, João P. Silva
Type-Z models, where charged leptons, up type quarks, and down type quarks each couple to a different scalar, are only possible when there are three or more Higgs doublets. We cons…
