CP violation in 2HDM and EFT: the ZZZ vertex
Hermès Bélusca-Maïto, Adam Falkowski, Duarte Fontes +2
We study the CP violating ZZZ vertex in the two-Higgs doublet model, which is a probe of a Jarlskog-type invariant in the extended Higgs sector. The form factor is evaluate…
Determination of the octant in long baseline neutrino experiments within and beyond the standard model
C. R. Das, Jukka Maalampi, João Pulido +1
The recent data indicate that the neutrino mixing angle deviates from the maximal-mixing value of 45, showing two nearly degenerate solutions, one in the lower oct…
Exploring the Quark Flavour Puzzle within the 3 Higgs Model
Nuno Rosa Agostinho, David Emmanuel-Costa, J. I. Silva-Marcos
We extend the standard model with two extra Higgs doublets. Making use of a symmetry principle, we present flavour symmetries based on cycle groups that oblige each Higgs dou…
The discrete charm of flavour and CP violation
G. C. Branco, M. N. Rebelo
We point out that in the Standard Model (SM) there is no explanation why is of order . A framework is described for explaining this small mixing,…
Spontaneous symmetry breaking in three-Higgs-doublet -symmetric models
D. Emmanuel-Costa, O. M. Ogreid, P. Osland +1
The talk summarises work done by the authors consisting of a detailed study of the possible vacua in models with three Higgs doublets with symmetry and without explicit CP vi…
Controlled Flavour Changing Neutral Couplings in Two Higgs Doublet Models
Joao M. Alves, Francisco J. Botella, Gustavo C. Branco +2
We propose a class of Two Higgs Doublet Models where there are Flavour Changing Neutral Currents (FCNC) at tree level, but under control due to the introduction of a discrete symme…
A Simple Method to detect spontaneous CP Violation in multi-Higgs models
O. M. Ogreid, P. Osland, M. N. Rebelo
For models with several Higgs doublets we present an alternative method to the one proposed by Branco, Gerard and Grimus, in 1984, to check whether or not CP is spontaneously viola…
