Jets and Photons Spectroscopy of Higgs-ALP Interactions
Alexandre Alves, A. G. Dias, D. D. Lopes
Axion-like particles (ALPs) and Higgs bosons can interact in scalar sectors beyond the Standard Model, leading the Higgs boson to decay into pairs of gluons and photons through the…

Probing ALP-Sterile Neutrino Couplings at the LHC
Alexandre Alves, Alex G. Dias, Diego D. Lopes
In this work, prospects to probe an overlooked facet of axion-like particles (ALPs) -- their potential couplings to sterile neutrinos -- are presented. We found that mono-photon se…

Fermion Mass Hierarchy and Double Seesaw Mechanism in a 3-3-1 Model with an Axion
A. G. Dias, J. Leite, D. D. Lopes +1
We present a model based on the gauge symmetry that relates the mass hierarchy of the fermions with the solution to the strong CP problem thr…
