A CP-conserving multi-Higgs model without real basis
, 2016 Models beyond the Standard Model (bSM) often involve elaborate Higgs sectors, which can be a source of CP-violation. It brings up the question of recognizing in an efficient way whether a model is CP-violating. There is a diffuse belief that the issue of

A New Avenue to Charged Higgs Discovery in Multi-Higgs Models [PDF]
Journal of High Energy Physics, 2014 Current searches for the charged Higgs at the LHC focus only on the $\tau\nu$, $cs$, and $tb$ final states. Instead, we consider the process $pp\to \Phi\to W^\pm H^\mp \to W^+ W^- A$ where $\Phi$ is a heavy neutral Higgs boson, $H^\pm$ is a charged Higgs

Discrete and continuous symmetries in multi-Higgs-doublet models [PDF]
Physical Review D, 2008 We consider the Higgs sector of multi-Higgs-doublet models in the presence of simple symmetries relating the various fields. We construct basis invariant observables which may in principle be used to detect these symmetries for any number of doublets.

Family Symmetries and Multi Higgs Doublet Models [PDF]
Symmetry, 2020 Imposing a family symmetry on the Standard Model in order to reduce the number of its free parameters, due to the Schur’s Lemma, requires an explicit breaking of this symmetry. To avoid the need for this symmetry to break, additional Higgs doublets can be introduced.

B->tau nu in multi-Higgs models with MFV [PDF]
, 2011 We analyse the $B \rightarrow \tau \nu$ decay in a generic two-Higgs doublet model satisfying the MFV hypothesis. In particular, we analyse under which conditions $\BR(B \rightarrow \tau \nu)$ can be substantially enhanced over its SM value, taking into account the constraints of $K \rightarrow \mu\nu$, $B \rightarrow X_s \gamma$, and $B_s \rightarrow \

BSM patterns in scalar-sector coupling modifiers
Journal of High Energy Physics, 2023 We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson fusion Higgs pair production at present and future colliders — where the signal is a ...
