Pseudoscalar contributions to Zh production at the LHC at 95 GeV and above

J. Dutta, P. M. Ferreira, S. Heinemeyer

In generalizations of the Standard Models with extended scalar sectors, pseudoscalar particles will contribute to associated production of the Higgs boson discovered at the LHC, $h…

New Symmetries of the Two-Higgs-Doublet Model

Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1

The Two Higgs Doublet Model invariant under the gauge group SU(2)xU(1) is known to have six additional global discrete or continuous symmetries of its scalar sector. We have discov…

2HDM interpretations of the CMS diphoton excess at 95 GeV

Duarte Azevedo, Thomas Biekötter, P. M. Ferreira

In both Run 1 and Run 2 of the LHC, the CMS collaboration has observed an excess of events in the searches for low-mass Higgs bosons in the diphoton final state at a mass of about…

Collider phenomenology of new neutral scalars in a flavoured multi-Higgs model

Pedro M. Ferreira, João Gonçalves, António P. Morais +3

In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signa…

Softly broken symmetries in the 2HDM -- an invariant formulation

Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1

Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separatio…

Phenomenology of a flavoured multiscalar BGL-like model with three generations of massive neutrinos

Pedro M. Ferreira, Felipe F. Freitas, João Gonçalves +3

In this paper, we present several possible anomaly-free implementations of the Branco-Grimus-Lavoura (BGL) model with two Higgs doublets and one singlet scalar. The model also incl…
